Parallel Class-E Resonant Inverters with a Common EMI Filter for Domestic Induction Cooker

This study proposes a method to parallelly connect 2 Class-E resonant inverters for domestic induction cookers. The setup consists of induction heating systems, which include a full-wave rectifier, an electromagnetic interference filter, 2 Class-E resonant inverters, and induction loads connected to each inverter. A PWM control circuit, which enables zero voltage switching (ZVS) and zero voltage and current switching (ZVDS). The aim of using this circuit is to produce a medium-frequency current that passes through the induction coil, thus causing the vessel to heat up through induction heating. Using a common electromagnetic interference (EMI) filter and pulse-width modulation (PWM) control circuit, this study shows a new way to reduce the functioning of systems. This paper provides instructions for constructing important parameters using a Class-E resonant inverter to minimize system complexity. This methodology provides a more pragmatic answer than conventional methods. Both inverters operated with a root mean square (RMS) voltage of 220 V, a frequency of 50 Hz, and an inverter power output of 1,500 W.
