STMicroelectronics STEVAL-IPFC02V1 PFC Kit
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 from STMicroelectronics consists of a power board with a 2-channel interleaved CCM-boost power stage, an auxiliary power supply, and a control board with an embedded STNRGPF02 digital controller. Additionally, it also includes a small adapter board for programming the STNRGPF02.
The STEVAL-IPFC02V1 PFC kit incorporates a 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 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.
