Abstract: The present disclosure provides a current sensor including: a shunt resistor provided between a first bus bar and a second bus bar, and a fastener coupled through the first bus bar, the second bus bar, and the shunt resistor. The first bus bar has a first through-hole, the second bus bar has a second through-hole, and the shunt resistor has a third through-hole. The first through-hole, the second through-hole, and the third through-hole are aligned with one another to allow the fastener to pass through the first to third through-holes.

Abstract: Forms of the present disclosure include an input end, and an output end connected to the input end to improve a power factor through the input end. The output end includes non-electrolytic capacitors formed at both sides of an electrolytic capacitor for output, and first inductors formed between the respective non-electrolytic capacitors and the electrolytic capacitor. Therefore, forms of the present disclosure may reduce a ripple current (current stress) at a PFC output end through a CL circuit formed at a left side with respect to the electrolytic capacitor, and reduce an input ripple current (input current stress) of a DC-DC converter through an LC circuit formed at a right side.

Abstract: An inverter for driving a motor of a vehicle mediating between a battery and a driving motor is disclosed. The inverter includes a power storage module, a power module, and a cooling module. The power storage module is configured to be supplied with power from the battery. The power module is configured to be supplied with power from the power storage module to transfer the power to the driving motor. The cooling module is configured to be installed between the power storage module and the power module to simultaneously cool the power storage module and the power module.

Abstract: A method for changing a capacitance value of an output capacitor of a power factor corrector (PFC) includes applying AC power to a power conversion circuit. It is sensed whether an instantaneous power failure occurs in the AC power. Output capacitors of the PFC of the power conversion circuit are connected in parallel to each other to increase capacitance values of the output capacitors, when it is sensed that the instantaneous power failure does not occur in the AC power.
