A multi output DC/DC converter includes a transformer having a primary side winding connected to an input side and a secondary side winding connected to an output side; a rectifying diode for rectifying an output of the secondary side winding; an output inductor having a first end connected to the rectifying diode; and a first output switching element and a second output switching element each having first ends connected to a second end of the output inductor, where a second end of the first output switching element and a second end of the second output switching element become first and second output stages outputting different voltages, respectively.

Multi output DC/DC converter and method for controlling the same

A DC-DC converter includes: a clamp capacitor having one terminal connected with a ground terminal of a voltage source; a switching circuit including first and second switches connected with each other in series between a positive terminal and the ground terminal of the voltage source, and third and fourth switches connected with each other in series between both terminals of the clamp capacitor; and a forward-flyback transformer including a plurality of primary coils connected between a first connection node between the first and second switches and a second connection node between the third and fourth switches.

DC-DC converter and control method thereof

Disclosed herein is a method and a system for controlling a generation output of a starter generator connected to an engine to transmit a rotary force in a hybrid electric vehicle. The method includes receiving, by a controller, vehicle state information for determining a driving mode of the vehicle after the vehicle starts, and determines the driving mode requiring an increase of the generation output from the vehicle state information; determining, by the controller, a need for the increase of the generation output to control a generation output variable for each driving mode; determining, by the controller, a torque command and a torque application time corresponding to a required output for each driving mode of the vehicle to control the generation output variable; and applying, by the controller, the determined torque command for the determined application time to control the generation output of the starter generator.
