This In general, telecommunication applications require low voltage, high current and reduced size power supplies. Selection of high switching frequency helps in the reduction of the DC-DC converter size. In this work, Digital PI (DPI) enables the Digital Pulse Width Modulation (DPWM) generator for generating high switching frequencies are developed and implemented using VHDL coding and Xilinx Spartan 3A DSP Field Programmable Gate Array (FPGA) kit. Hardware result of voltage regulation depicts the superiority and robustness of the proposed DPI enabled DPWM (MD-DPWM) methods under line and load disturbances. The MD-DPWM technique can be used to generate a very high switching frequency up to 1 MHz and more. Also the MD-DPWM proves to be cost effective, as it consumes low power and area.
