Abstract

A generator is studied that consists of a low-power source with an insufficient DC voltage level for the consumer, a semiconductor switch on an IGBT transistor, an inductive-capacitive link, a thyristor that is switched on by dynistors, and a pulse transformer. The generator is designed to power various consumers with high-power current pulses with a repetition frequency of up to 100 Hz or more. Experimental studies of a generator prototype model showed that in comparison with a low-power source (22 W, 13.8 V), the pulse power and voltage values for a consumer were 2.47 kW and 1122 V. At the same time, the current pulses had an amplitude of 2.2 A, a duration of 20 μs, and a repetition frequency of 50–167 Hz in the consumer’s resistance (510 Ω) at a source voltage of 13.8–22.8 V. As the DC voltage of the power supply increased, the number of capacitor-charging current pulses decreased, while the frequency of current pulses in the load increased. The maximum voltage at the capacitor during its charging is 3–5 times higher than the source voltage.

摘要

研究了一种发电机，该发电机由低功率源组成，该低功率源的直流电压电平不足以供用户使用，IGBT晶体管上的半导体开关，电感电容链路，可控硅导通的晶闸管和脉冲变压器。该发生器设计用于以高达100 Hz或更高的重复频率的高功率电流脉冲为各种用户供电。发电机原型模型的实验研究表明，与低功率电源（22 W，13.8 V）相比，消费者的脉冲功率和电压值为2.47 kW和1122V。同时，电流脉冲具有源电压为13.8-22.8 V时，使用者电阻（510Ω）的幅度为2.2 A，持续时间为20μs，重复频率为50-167 Hz。随着电源DC电压的增加，电容器充电电流脉冲的数量减少，而负载中电流脉冲的频率增加。电容器充电期间的最大电压比电源电压高3–5倍。
