大功率高压输入的IGBT高频直-直变换器
A High-Power DC-DC Converter for High Frequency High-Input Voltage Using IGBT
摘要
Abstract
For the high frequency and high-input-voltage (sometimes reaching several kilo-volts) converter, its switching devices - IGBTs′ voltage rating can not suit this requirement. In this paper, a new cascaded-inverter-units structure is proposed, in which the high-input-voltage is divided into several parts and each part corresponds to one DC-AC converter. So the IGBT′s operating voltages are equal to the voltage of each divided part. In order to increase the output power, the output-rectifier-diodes usually are used in parallel, a method to balance the current by changing the linking type between the transformer secondary windings and the output-rectifier diodes is recommended. This method fully utilizes the transformer leakage inductance to realize the current-sharing function. In this paper, operation of a high-input voltage, high-power DC-DC converter is described. Both experimental and simulation results are shown for a small-full-scale-model converter.关键词
