Two -way ACDC circuit

The utility model provides a two -way ACDC circuit, include: 12 arteries and veins rectifier transformer carries out the electric pressure to input alternating?current?power?supply and alternaties, and the angle joint winding on the vice limit of 12 arteries and veins rectifier transformer is connected with the input of PWM power, and the star on the vice limit of 12 arteries and veins rectifier transformer connects the winding to be connected with the input of 6 arteries and veins powers. The utility model discloses a two -way ACDC circuit adopts 12 arteries and veins transformers to link together IGBT PWM power of constituteing and the 6 arteries and veins powers that diode cluster becomes, is 12 arteries and veins rectifier systems when the rectification, has the characteristics that the loss is low, the harmonic is low, be PWM contravariant mode when the contravariant state, have the characteristics that the harmonic is low, power factor is high. 本实用新型提出了种双向AC/DC电路，包括：12脉整流变压器，对输入交流电源进行电压等级变换，12脉整流变压器副边的角
