Falownik klasy E (30 MHz, 300 W) z niskostratnym drajwerem hybrydowym

Abstract

This paper presents performance, property analysis, and experimental research of a new low-losses Hybrid Driver for DE-Series MOSFET power transistors. The new driver can operating in (30MHz, 300W) high-frequency class E inverter. The new hybrid driver design has been developed as a PCB circuit on a thermal clad technology with the use of discrete low power components. In the project tested three integrated drivers IXYS Corporation and additionally two discrete drivers and one hybrid driver have been designed. Additionally, in this paper presents characteristic power input by the drivers (fig.5) for three operating states: at idle, at capacitance load 3 nF and at gate MOSFET 501N16A load. Also in this paper presents voltage waveforms (fig.6) and pictures of the thermal camera. At the end presents the measurements of parasitic parameters (inductances L DR , capacities C OUT and resistances R DR), switching and propagation times for all drivers.
