Beschreibung
The STEVAL-TTPPFC01 offers a very high flat efficiency PFC solution in a full digital three-channel interleaved totem-pole topology. A conversion efficiency higher than 99.1% using ST MDmesh DM6 superjunction power MOSFETs is obtained, as well as a very high power factor and low THDi.The PFC operates in the zero voltage switching (ZVS) resonant mode with hysteresis current control, which is fully implemented in the STM32G474QE microcontroller, thanks to the integrated DACs, fast comparators, and high-resolution timer peripheral HRTIM, to ensure a high dynamic and precise cycle-by-cycle current control.The STEVAL-TTPPFC01 evaluation kit is a modular solution, which consists of: a power board, which contains all the main passive devices and all the daughter boards plug connectors; a control board, which embeds the STM32G474QE microcontroller; an auxiliary power supply board, which generates all the voltages for driving, sensing, MCU, etc.; three high-frequency half-bridge boards; a low-frequency half-bridge board.
