Abstract:Abstract. Digital pulse width modulation (DPWM) has advantages of strong anti-interference ability, high efficiency and good flexibility, therefore it has been widely used in switching power supply, communications, power control and transform and other fields. This paper proposed a high resolution DPWM control circuit based on field programmable gate array (FPGA), which solved the problem of low resolution and instability of the traditional DPWM control circuit. The principle of the proposed circuit is present… Show more
