The Effect of Switching Dead Time on the Output of Inverter

스위칭 데드타임이 인버터 출력에 미치는 영향

The dead time which is inserted in switching signals of PWM voltage source inverters distorts its output. As a result, the deviations of real fundamental voltage and phase compared with the reference are occurred. And also the harmonics on its output are increased. In this paper, numerical analysis of the error voltage on the output of inverter according to the switching dead time is presented. And the calculation results of fundamental voltage gain and phase deviations are presented
