Using FPGA and CPLD ICs to Achieve High-Frequency PWM

Abstract:

Article Preview

PWM (Pulse width modulation) has been widely used in power converter control. This paper is the development of a high-frequency PWM generator architecture for power converter control using FPGA and CPLD ICs. The proposed architecture is based on a special design synchronous binary counter and can be easily interfaced to a microcontroller or DSP system. The resulting PWM frequency depends on the target FPGA or CPLD device speed grade and the duty cycle resolution requirements.
