3KW三相稳压逆变电源——三相纯正弦逆变芯片HT3117

该三相稳压逆变电源模块采用 DC/AC/工频变压器 两级功率变换架构,具有过欠压、过流及过热保护功能,控制芯片HT3117,驱动芯片IR2110,该模块采用输入输出隔离的方案.
一、a)逆变电源模块DC/AC部分

控制板:170mm、76mm
功率版:210mm、131mm
散热片:219mm、149mm、38mm
加散热片后板子整体高度为:84mm
    b)三相工频变压器

二、1) 输入额定电压:DC48V  
    2) 输入额定电流:60A
    3) 输出电压:AC380V
    4) 输出频率:50Hz  
三、三相工频变压器参数如下:
    现用变压器为1.5KW
    变比:20/380  
    原边漏感:141uH
    长宽高分别为:260mm、120mm、230mm
    绕线为铝线,变压器原边是三角型联接,副边是星型联接
现在板子承受能力最大电流为60A,若想做成更高功率的,原理是一样的,只需更改开关管.
