Title: Quick implementation of Pule Wise Modulation(PWM), Pulse Frequency Modulation(PFM) and mixed PWM/PFM on FPGA chip
Abstract: This paper proposes a method to successfully embedded three control waveforms, PWM (Pulse Width Modulation), PFM (Pulse Frequency Modulation), and PWM-PFM (pulse width frequency modulation), into an FPGA (Field-Programmable Gate Array) chip. The three types of control modulation are generally used in power supply design. A single function IC with PWM or PFM is already on the market. However, there is no such chip on the market to integrate these three control modulation functions into one IC chip. An HDL (Hardware Description Language) algorithm that can satisfy the above three functions at the same time is proposed and implemented in the FPGA chip. We also proposed several experimental measurements to prove that these three functions do coexist in the FPGA chip.
