铝箔腐蚀用大功率变频电源

Abstract

研制了用于电解电容器阳极铝箔腐蚀的变频电源.设计了一种应用单片机控制的高频开关电源和用电子开关桥换相的低频变频、多波形大功率电源.该电源不需要庞大、笨重的变压器,而且频率下限不受限制,甚至可低至1Hz以下.

A new variable frequence and multi-wave power supply used to aluminum foil corrosion is introduced.The switching supply power supply controlled by the microcontroller and Variable Frequence in low band and multi-wave、big power supply controlled by the electronic switch bridge for changing phase were designed.This power supply does not need bulky and cumbersome transformer,and the frequency at lower limit is not limited,even lower than 1Hz.
