Induction heating for domestic usage is quite popular and in some countries, it is a highly cost-sensitive product. A single IGBT (Insulated Gate Bipolar Transistor) quasi resonant power stage is the most popular topology for this application. In this paper we explain method in which the topology works reliably irrespective of widely varying input voltage, open loop operation and inconsistent utensil...
In this paper, two new topologies are proposed for multilevel inverters. The proposed topologies consist of a combination of the conventional series and the switched capacitor inverter units. The proposed topologies reduce the number of switches and isolated dc voltage sources, the variety of the dc voltage source values, and the size and cost of the system in comparison with the conventional topologies...
This paper presents an overview of research on a novel AC drive with fully integrated matrix converter that implements bus bars and active gate driving technique for overvoltage minimization during power switch commutation. This overview includes main features of power IGBT gate driving, principles of bus-bars, as well as active gate driver for power IGBT overvoltage protection.
