Abstract: PURPOSE: A governor controller using power information is provided to control the current of governor actuator which supplies fuel to an engine, thereby controlling the constant speed by the frequency stabilization at the time of varying load. CONSTITUTION: A governor controller using power information includes a speed comparing unit (110), a command current control unit (120), a current comparing unit (130), and a drive current control unit (140). The speed comparing unit is inputted with the command speed of an engine (10) and the actual speed of the engine, and outputs the speed difference value which is the difference value between the command speed and the actual speed. The command current control unit outputs the speed difference value by calculating the speed difference value as the command current of actuator (20). The current comparing unit is inputted with the actual current of the command value and the actuator, and outputs the current difference value which is the difference value between the command current and the actual current. The drive current control unit outputs the current difference value by calculating the speed difference value as the drive current of the actuator.

Abstract: PURPOSE: A synchronous DC/DC converter of a zero voltage switching mode using a tab transformer is provided to minimize rectification loss by forming switching devices of a rectifier part by using a MOSFET(Metal Oxide Semiconductor Field Effect Transistor) switch instead of a diode. CONSTITUTION: One end of a chopper switch(110) is connected to one end of a DC input voltage. An inverter unit(120) is connected to the other end of the chopper switch and one end of an input voltage. The inverter unit outputs an AC voltage by switching the input voltage. One end of a free wheeling device(130) is connected between the chopper switch and the inverter part. The other end of the free wheeling device is connected to the other end of the DC input voltage. The free wheeling device forms reflux pass in an off-state of the chopper switch. A tap transformer(140) transforms the AC voltage. A rectifier(150) is connected to an output end of the tap transformer. The rectifier performs a switching operation through synchronization with the inverter unit.
