การวิเคราะห์วงจรอินเวอร์เตอร์เรโซแนนซ์แบบขนานและแบบผสมขนานอนุกรม

Abstract

This article presents the analysis of a resonant inverter that uses series-parallel (SPLR) and parallel (PLR) LC tanks, respectively. As a power load, pure resistance is considered. Analysis of the single and three-phase SPLR inverters considers 60 kHz and 90 kHz switching frequencies. For the single-phase PLR inverter, the switching of frequency 50 kHz is considered. The zero-voltage switching (ZVS) is employed to reduce the switching losses. Also, the resulted effects of harmonics and power factors are investigated. Simulation results using Pspice and Psim as well as experimental results are presented.
