Abstract:
The demand for lighter and more compact power converters is an opportunity for reducing their costs and environmental footprint. This work proposes an analytical method for the design of a finite input inductance class E inverter which is a fundamental topology in Very High Frequency (VHF – 30MHz to 300MHz) power converters. Validation of the method is performed through the fabrication of a 100W inverter operating at 34.5MHz, for Wireless Power Transfer (WPT) through Magnetic Resonant Coupling (MRC). An accurate model based on Electro-Magnetic (EM) simulation and high frequency (HF) characterization of passive components is presented.
