Comparative Study of Single Source Boosted Bipolar PWM Half-Bridge Inverter and Single Source Boosted Bipolar PWM H-Bridge Inverter

This paper compares a single source boosted bipolar PWM half-bridge inverter with a single source boosted bipolar PWM H-bridge inverter. Using the H-bridge inverter as a benchmark, the paper draws a comparison between the two topologies by evaluating the system performance and providing a comparative analysis. Both inverters are fed by a single DC source and employ a boost converter to maintain constant output voltage level over a variable load range. PSIM simulation software is used to examine the system performance of half-bridge inverter and compares it against its H-bridge counterpart for various performance parameters. Simulations demonstrate that half-bridge inverter is more power efficient and yields lower THD due to its smaller number of switches in the inverter's bridge.
