    • Abstract
  • This paper introduces the advantages of designing the inverter power supply PWM waveforms based on CPLD/FPGA with VHDL.It also discusses the principle and three methods for designing PWM waveforms with VHDL.The VHDL program for PWM waveforms based on ROM to be good real time is presented in this paper and is simulated by Active-VHDL.The stimulating and testing results show that PWM waveforms realized by VHDL possess good adjustable,flexible control property and easily attaining digital controller of PI or PID.
