摘要：A system and method are disclosed for providing a high efficiency bypass circuitfor multi-stage direct current to direct current (DC-DC) converters used in batterypowered systems. When the system is operating in a battery mode, the vehicle powersource is unplugged from the power supply input connector and the external battery isconnected in its place. The system uses a relay to bypass the flyback converter so as toconnect the boost converter output directly to the output terminals. The system uses asingle control signal to: 1) energize the relay connecting the boost converter outputdirectly to the output terminals, 2) adjust the boost converter circuit to cause the boostconverter to deliver a voltage equal to what the flyback converter would have delivered,and 3) disable the flyback converter.
