Abstract

We have proposed an inductor commutation soft-switched PWM inverter (ICSI) and the carrier frequency modulated ICSI (FM-ICSI) without sensors for the current and voltage. It is realized by connecting a series circuit with an inductor L_ZC and a capacitor C_ZC between the output terminals of the conventional hard switched inverter (CHIS), and by connecting a capacitor C_R in parallel with each main switch. The commutation elements L_ZC, C_ZC and C_R control the magnitude of the circulating current, short current and efficiency of ICSI and FM-ICSI. The circulating current always flows through the main switches and L_ZC and C_ZC from the dc source to realize soft switching. Therefore, in this paper, the relations of the commutation elements and these currents are analyzed and verified experimentally for design of ICSI and FM-ICSI.
