A Buck Converter Based Reduced Voltage Starter for DC Oil Pumps

摘要：

Designed a Reduced Voltage Starter for DC oil pumps in power plant, which is a Buck Converter based DC-motor soft Starter/Stopper with 220VDC power supply. In this paper, the main circuit, working principle and operating sequences of the switches of the device are clarified; and the design of each circuit unit is briefed; the transient of Buck Converter are analyzed and the snubbers for the Buck Converter are designed; at last the load test results of 55kw device are sketched. After running in a number of power plants, its been proved that the device is an upgrade for traditional Rotor Resistance Starter, for its stability, reliability, efficiency, and intelligence.
