摘要

本文对大功率整流器作为焊接设备电源的可行性进行了研究。将采用软件产生的脉宽调制(PWM)和软件实现的锁相环(PLL)等现代数字控制技术。由于采用了先进的单片机(MCU)，数字和模拟电路的设计可以减少到最低限度。电源部分采用6个igbt的三相桥式结构(B6)实现，开关频率为15.625 kHz。由于权力结构的二元性，两个能量方向都有可能实现。该研究包含数学分析和模拟，并作为这些研究的结果，描述了一个约15千瓦的原型。

Feasibility study of a three phase rectifier with sinusoidal net currents

This paper deals with a feasibility study for a power rectifier, which was designed as a power supply for welding equipment. Modern digital control techniques such as software generated pulse width modulation (PWM) and phase locked loop (PLL) realized in software, will be employed. With the use of an advanced single chip microcontroller (MCU) digital and analog circuit design could be reduced to a minimum. The power part is realized as a three phase bridge structure (B6) with six IGBTs with a switching frequency of 15.625 kHz. Due to the duality of the power structure, it is possible to realize both energy directions. The study contains mathematical analysis and simulation, and as a result to these studies a description of a prototype with about 15 kW.<>
