Full bridge DC-DC converter that applies current doubler

摘要

A full bridge DC-DC converter to which a current doubler is applicable is provided and includes a transformer and a switching circuit that converts a high direct current voltage into a high alternating current voltage and then outputs the high alternating current voltage to the primary side of the transformer. In addition, an output circuit receives and processes the output of the secondary side of the transformer and supplies the processed output to an electric load. The output circuit includes a first inductor, a first contact resistor, a second inductor, a second contact resistor, a first diode, a third contact resister, a second diode, and a fourth contact resister.

1. A full bridge direct current-direct current (DC-DC) converter to which a current doubler is applicable, comprising:
a transformer that reduces a substantially high alternating current (AC) voltage supplied to a primary side thereof and outputs the AC voltage to a secondary side thereof; a switching circuit that converts a transmitted substantially high DC voltage into a substantially high AC voltage and outputs the substantially high AC voltage to the primary side of the transformer; and an output circuit that receives and processes the output of the secondary side of the transformer and supplies the processed output to an electric load, the output circuit including,
a first inductor having a first end connected to a first end of the load side;a first contact resistor formed by connecting a second end of the first inductor and a first end of the secondary side of the transformer;a second inductor having a first end connected to the first end of the load side;a second contact resistor formed by connecting a second end of the second inductor and a second end of the secondary side of the transformer;a first diode having an anode connected to a ground line which is the second end of the load side;a third contact resister formed by connecting a cathode of the first diode and electric contacts of the first inductor and the first contact resistor;a second diode having an anode connected to a ground line which is the second end of the load side; anda fourth contact resister formed by connecting a cathode of the second diode and electric contacts of the second inductor and the second contact resistor.
