  • STEVAL-IPE010V2
    Energy meter demonstration kit motherboard based on the STPMC1

    The purpose of the demonstration board is to provide an evaluation platform for the STPMC1 and STPMS2L devices, but it can also be used as a starting point to design a Class 1 meter for 2 to 4-wire power line systems using delta or wye service.

    The STPMC1 is a metering ASSP implemented through an advanced 0.35 μm BCD6 technology.

    The STPMS2L is an ASSP designed as a building block for single or multi-phase energy meters.

    The STEVAL-IPE010V2 board is the motherboard based on the STPMC1 and works in conjunction with up to 5 STEVAL-IPE014V1 daughterboards (to be ordered separately), each with an STPMS2L mounted to sense the voltage and current of each phase.

    Each phase is monitored by an independent daughterboard, in which an autonomous power supply is provided to the board itself and, once it is connected, also to the motherboard.

    On this board, the STPMS2L device senses the phase current through a CT or a shunt sensor, and the phase voltage through a voltage divider.

    The presence of dedicated networks greatly reduces the sampling (aliasing) noise and the crosstalk noise between voltage and current channels, increasing meter precision. The STPMS2L produces a sigma-delta stream, sent

    together with the supply voltage, to the STPMC1 through a card edge connector.

    The STEVAL-IPE010V2 motherboard receives the sigma-delta streams from the daughterboards which are further elaborated by the STPMC1. This device, from a 4.194 MHz crystal oscillator, provides a common clock with programmable frequency to all the daughterboards.

    The STEVAL-IPE010V2 motherboard, through a 10-pin flat cable connector, can be interfaced to a microprocessor board to implement advanced metering features (multi-tariff, data management and storage, communication, etc). It also has stepper motor connectors for simple energy meter implementation.

  • STEVAL-ISV005V2
    240 W photovoltaic battery charger based on the SPV1020

    The STEVAL-ISV005V2 demonstration board is mainly based on the SPV1020 device, a monolithic DC-DC boost converter designed to maximize the power generated by photovoltaic panels independently of temperature and amount of solar radiation.

    The optimization of the power conversion is obtained with an embedded logic which performs the MPPT (max power point tracking) algorithm on the PV cells connected to the converter.

    One or more converters can be housed in the connection box of the PV panels, replacing the bypass diodes. Since the maximum power point is locally computed, the efficiency at system level will be higher than that of conventional topologies, where the MPP is computed in the main centralized inverter.

    For a cost-effective application solution and miniaturization requirements, the SPV1020 embeds the power MOSFETs for active switches and synchronous rectification, minimizing the number of external devices. Furthermore, the 4-phase interleaved topology of the DC-DC converter renders unnecessary the use of electrolytic capacitors, which would severely limit the lifetime.

    The SPV1020 works at fixed frequency in PWM mode, where the duty cycle is controlled by the embedded logic running a “Perturb & Observe” MPPT algorithm. The switching frequency, internally generated and set by default at 100 kHz, can be tuned externally, while the duty cycle ranges from 5% to 90% with a step of 0.2%.

    Safety of the application is guaranteed by stopping the drivers in case of output overvoltage or overtemperature.

    The bypass diodes SPV1001N40 guarantee very high application efficiency even when the PV panel voltage is lower than the UVLO threshold of the SPV1020 (6.5 V) and the connection is in series consisting of two or more PV panels.

    The SEA05 is connected to the output stage of the application and is used to implement the output current limitation (not available with the SPV1020 alone) through the current sensing resistors R9 and R10.

  • STEVAL-ISV006V2
    Up to 5 W solar battery charger with embedded MPPT based on SPV1040

    The STEVAL-ISV006V2 demonstration board is based on the SPV1040 high efficiency solar battery charger with embedded MPPT. The SPV1040 device is a low power, low voltage, monolithic step-up converter with an input voltage range from 0.3 V to 5.5 V, and is capable of maximizing the energy generated by even a single solar cell (or fuel cell), where low input voltage handling capability is extremely important.

    Thanks to the embedded MPPT algorithm, even under varying environmental conditions (such as irradiation, dirt, temperature) the SPV1040 offers maximum efficiency in terms of power harvested from the cells and transferred to the output.

    The device employs an input voltage regulation loop, which fixes the charging battery voltage via a resistor divider. The maximum output current is set with a current sense resistor according to charging current requirements.

    The SPV1040 protects itself and other application devices by stopping the PWM switching if either the maximum current threshold (up to 2 A) is reached or the maximum temperature limit (up to 155 °C) is exceeded.

    The STEVAL-ISV006V2 demonstration board is supplied by a PV panel with PPKof 200 mW, which can be replaced with PV panels with PPKup to 5 W (VOC < 5 V) depending on application requirements.

    The output load is a 220 mF, 5.5 V super-capacitor that can be replaced with lead-acid, NiCd or NiMh rechargeable batteries (max voltage = 5 and > VOCof the selected PV panel).

    The demonstration board provides a simple charge status indicator using 2 LEDs, and 3 trimmers are available to allow setup according to the specific application requirements.

  • STEVAL-ISV008V1
    300 W PV converter demonstration board to be integrated into a photovoltaic panel based on the SPV1020

    The STEVAL-ISV008V1 demonstration board contains 3 SPV1020s in the same PCB and is suitable for distributed PV panels with 3 isolated strings. The outputs of the SPV1020s can be connected in parallel (STEVAL-ISV008v1 default setting) or in series, despite the pairs of independent inputs. For the STEVAL-ISV008v1 only the output parallel connection is allowed.

    The SPV1020 is a monolithic DC-DC boost converter designed to maximize the power generated by photovoltaic panels independent of temperature and amount of solar radiation.

  • STEVAL-ISV015V1
    Up to 2.5 W solar USB supply based on the SPV1040 and LD39050

    The STEVAL-ISV015V1 demonstration board is a solar harvester system designed to supply USB devices and is based on the ST devices SPV1040 (solar voltage boost converter) and LD39050 (voltage regulator with low quiescent current and low noise). The SPV1040 is a high efficiency, low power and low voltage monolithic step-up converter that operates over a 0.3 V to 5 V input voltage range, therefore allowing the use of even a few solar cells in all portable applications where the capability of handling low input voltages is of utmost importance. Despite the variation of several conditions throughout the day (such as irradiation, dirt, temperature, etc.) the SPV1040 allows the achievement of maximum efficiency (90% typ.) in terms of power harvested from the cells and transferred to the output thanks to the embedded MPPT algorithm. The SPV1040 allows the output voltage to be regulated by using an external resistive divider up to 5.2 V, limiting the current supplied to protect the battery and the measuring of input current and voltage to research the maximum power point through a dedicated input pin. Furthermore, the device can be shut off by driving an XSHUT pin to a logic level low, in order to save power when its working mode is not required. Self protection features like overtemperature and overcurrent at the input are implemented. The LD39050 provides 500 mA maximum current from an input voltage ranging from 1.5 V to 5.5 V with a typical dropout voltage of 200 mV. It is available in a fixed output voltage version from 0.8 V up to 4.5 V (100 mV steps), or adjustable between 0.8 V and Vin- Vdrop. The ultra low drop-voltage, low quiescent current and low noise features make it suitable for low power battery-powered applications. Stability is ensured using ceramic capacitors. The power supply rejection is 65 dB at low frequencies and starts to roll off at 10 kHz. An enable logic control function puts the LD39050 in shut-down mode allowing a total current consumption of lower than 1 μA. The device also includes short-circuit constant current limiting and thermal protection.
