Continuous Conduction Mode Pre-Converters Module for Power Factor Controller
This compact module shown here is a Continuous Conduction Mode (CCM) Power Factor Correction Step up Pre-Converter. All-important inputs and output pins are broken out for use in your application, making this board hackable! Please refer to the datasheet of the NCP1654 chip for easy alteration and configuration of the board as per requirements. This board controls the power switch conduction time (PWM) in fixed frequency mode and is dependent on the instantaneous coil current. This module drastically simplifies the PFC implementation scheme. It also integrates high safety features that make the NCP1654 module ideal for robust and compact PFC stages like an effective input power runaway clamping circuit. Please refer to the application schematic to create a powerful PFC using this pre-driver module. The chip is available with various options for frequency such as 65Khz, 133Khz, and 200Khz. Choose the appropriate chip as per frequency requirement This project is tested with a 65Khz oscillator chip.
