STMicroelectronics STEVAL-IPFC02V1 PFC Kit evaluates STNRGPF02 digital controller that is designed specifically for interleaved PFC boost topologies. This development kit features the performance of analog cycle-by-cycle current regulation and the flexibility of digital control. This is to generate sinusoidal supplies with a high power factor and very low harmonic distortion. The STEVAL-IPFC02V1 kit consists of a power board with 2-channel interleaved CCM-boost power stage, auxiliary power supply, and a control board with embedded STNRGPF02 digital controller. Additionally, it also includes a small adapter board for programming the STNRGPF02.
The STEVAL-IPFC02V1 PFC kit incorporates cooling function, inrush current limiter, and 47Hz to 63Hz line frequency range with 2kW at 230V maximum output power. This PFC reference design kit offers the burst-mode operation, overvoltage protection, overcurrent protection, and thermal protection features. The aim of this reference design is to provide a flexible PFC converter that can accept a wide input range (90V-265V) for high power (>600W) applications.
