The STEVAL-IPFC02V1 2 kW interleaved PFC reference design features the performance of analog cycle-by-cycle current regulation and the flexibility of digital control to generate sinusoidal supplies with very high power factor and very low harmonic distortion.


Digital power control is based on the STNRGPF02 digital PFC controller, which can drive up to two interleaved PFC channels using mixed signal (analog and digital) average current mode control in CCM at fixed frequency.


The 2 kW interleaved PFC reference design consists of a power board with 2-ch interleaved CCM boost power stage, auxiliary power supply, a control board with embedded STNRGPF02 digital controller and a small adapter board for programming the STNRGPF02.


eDesignSuite is the tool available in the ST website to configure the STNRGPF02 according to specific design requirements for each interleaved PFC.
