Nonlinear Dynamic Behaviors in Voltage-Mode Controlled Single-Phase Half-Bridge Inverters via Varying Input Voltage

Power circuit is a voltage-mode controlled single-phase half-bridge inverter. This work investigates nonlinear dynamic behaviors with a valid and novel approach. Firstly, the operational principle of a single-phase half-bridge inverter is examined and mapping state-space equations are generated. Additionally, the SIMULINK tool for mathematical simulation and IsSpice for approximately physical simulation are adopted. The input DC voltage is changed to analyze the nonlinear dynamic behaviors waveforms of the inductor current and output voltage. Simulation results clearly demonstrate that SIMULINK and IsSpice provide consistent results and validate the mathematical models.
