Abstract:

A programmable PWM controller based on the CPLD is designed.Programmable design makes it possible to be interfaced with a microprocessor.This design,as a basic kernel module,can be called by the user in other CPLD or FPGA applications.Simulation waveforms and experimental results prove that the design meets the expected requirements.
