基于半桥结构的新型高速铁路功率调节器
A Novel Power Conditioner Based on Half-Bridge Converter for High-speed Electrified Railway System
摘要
Abstract
With the high-speed, high-power load development of high-speed electrified railway, power quality of the electric traction system become more and more critical. This paper proposed a novel solution based on half-bridge converter railway power conditioner likely applied to high-power compensation. The compensation system consisted of two half-bridge converters connected by two joint capacitors in series, and then it was linked with two traction power arms through step-down transformers. Compared with traditional power regulator, the power compensating unit required only two pairs of power switches and two capacitors, so it reducd four power switches. Accomplish the same function in the premise, it reduced half of active capacity, hardware cost and complexity, and increased the reliability of compensation device. This would greatly be of benefit to form the modular high-power devices, and was corresponding to large-capacity compensation of high-speed railway with good prospects. Simulation and experimental results had effectively verified the proposed structure and its control method.关键词
