Description
The STEVAL-10MLPVCB is a 10 kW multilevel buck/boost converter with MPPT evaluation system.
It is based on a three-level power stage that is configured using flying capacitors and SiC 650 V MOSFETs in buck/boost mode.
In buck mode, the input voltage range is 425-850 V and the nominal output voltage is 400 V, with active current sharing on a common 400 V dc bus for feeding the battery bank or an inverter.
The same evaluation board can function as a boost mode with a nominal output voltage of 800 V and an input voltage range of 250-800 V by changing a few resistors in hardware and firmware for boost operation.
The STEVAL-10MLPVCB includes dual independent input channels and achieves a peak power conversion efficiency of > 99% using a perturb and observe MPPT algorithm.
A single 32-bit STM32G474RE Arm MCU controls MPPT, dual-channel conversion, flying capacitor balancing, output regulation and protection mechanisms.
The evaluation board is targeted at renewable and energy storage applications.
