The simplified model of the Class E inverter with the PWL model of the MOSFET turn off

Abstract

The paper presents the simplified model of the Class E inverter in which the MOSFET transistor is based on the piecewise‐linear (PWL) model. The model does not contain inductances. The PWL description makes it possible to obtain the model in the form of general closed formulae. The general formulae have been obtained by means of MATHCAD and verified with the IsSPICE^® simulator. The analysis of MOSFET switching performance in the active region at the constant load current is delivered. The work is a successive step in the systematic research of the Class E inverter as a supplying source in high frequency levitation heating/melting systems. The equivalent RL parameters of the load in such systems vary across a relatively wide range.
