A Design and Implementation of Edge Controller for SPWM Waves
SPWM (Sinusoidal Pulse Width Modulation) waves are commonly used in the control of frequency conversion and test system.This paper presents a method which can control SPWM waves rising/falling time for the requirements of controlled edge.This function mainly for a high power device test systems.First,SPWM waves are generated by a generator programmed by LabVIEW,and the SPWM waves’ dead time and frequency of carrier signals and modulation signals can be easily regulated by LabVIEW.Second,SPWM waves rising /falling time is adjusted by edge controller.The experimental results indicate that SPWM waves edge time adjusts from 0.1 s to 12 s can be achieved using this design.
