双向DC-DC转换器

Two-way DC-DC converter

US-7177163-B2

用于双向直流电压转换。

专利摘要

整流元件与低压侧开关部分4中的开关元件4-1至4-4并联连接,整流元件与高压侧开关部分5中的开关元件5-1至5-4并联连接。LC谐振电路6设置在变压器3的高压侧绕组线3-2与高压侧开关部分5之间;在初级侧和次级侧流动的电流被改变为正弦波;并且在电流的过零点附近执行开关。

Original abstractRectifying elements are connected in parallel with switching elements 4 - 1 through 4 - 4 in a switching section 4 for the lower voltage side and rectifying elements are connected in parallel with switching elements 5 - 1 through 5 - 4 in a switching section 5 for the higher voltage side. An LC resonant circuit 6 is provided between the winding wire 3 - 2 for the high-voltage side in the transformer 3 and the switching section 5 for the higher voltage side; currents which flows on the primary side and the secondary side is changed into a sinusoidal one; and switching is executed in the vicinity of the zero crossing points of the currents.
