Abstract—This paper presents bifurcation and chaos in a PWM currentmode H-bridge inverter. This inverter exhibits various interesting bifurcation phenomena. First, we briefly explain the behavior of a PWM currentmode H-bridge inverter from viewpoints of the switched dynamical system. In order to analyze the circuit dynamics we derive a return map exactly. Using this map, the stability of the pe...

DC-DC converters have been applied to industrial applications widely during the past few decades. With rapid development of technology, negative output (N/O) dc-dc converters play an important role in the industrial fields, such as regenerative braking system (RBS) of DC motors for hybrid electric vehicles, signal generator and data transmission interface, neutral point clamping power electroni...

AbstructA novel soft-switched inverter topology is derived from the passively clamped quasi-resonant link (PCQRL) circuit. By introducing magnetic coupling between the two resonant inductors, the number of auxiliary switches can be reduced from two to one, and only a single magnetic core is required for the resonant dc link. An analysis of this novel PCQRL topology with coupled inductors is pre...

This article presents a new circuit topology for high voltage gain active switched boost quasi Z-source inverter (qZSI) and pulsewidth modulation (PWM) technique.
