STEVAL-ISV004V2240 W PV converter for photovoltaic panels based on the SPV1020
The STEVAL-ISV004V2 demonstration board is based on the SPV1020 monolithic DC-DC boost converter in a PSSO36 package designed to maximize the power generated by photovoltaic panels, independent of temperature and amount of solar radiation.
Optimization of power conversion is obtained through embedded logic, which performs the MPPT (max power point tracking) algorithm based on monitoring of the voltage and current supplied by the PV cells.
The precision of the algorithm is guaranteed by a 10-bit ADC for current and voltage sensing.
For cost-effectiveness and miniaturization of the application, the SPV1020 embeds 8 power MOSFETs for active switching and synchronous rectification, minimizing the number of external components required. The 4-phase interleaved topology of the DC-DC converter means that electrolytic capacitors can be avoided, which would otherwise severely limit system lifetime.
PWM switching (duty cycle varies between 5% and 90%, with 0.2% accuracy) is regulated by default at 100 kHz by an internal oscillator, but is programmable between 50 kHz and 200 kHz via an external resistor.
Application safety is ensured by stopping the PWM switching in case of output overvoltage (set by external trimming), overcurrent (internally regulated at 4 A for each channel) and over-temperature (160 oC).
