Abstract

The invention relates to a device for supplying power from a vehicle battery to the outside of a vehicle and a vehicle bidirectional charging apparatus including the same. The apparatus includes an inverter circuit having a bridge circuit including a plurality of switching elements, and converting a received direct current into an alternating current by switching of the switching elements, and outputting the alternating current, and a controller controlling an on / off state of each switching element by pulse width modulation. When the value of the output AC current output to the load is greater than a preset reference value, or the value of the input DC current input to the inverter is greater than a preset reference value, the controller changes the duty ratio of each switching element to reduce the output AC voltage output from the inverter. When the value of the reduced output AC voltage is equal to or less than a preset reference value, the controller stops the power conversion operation of the inverter.

Description

technical field [0001] The present invention relates to a device for supplying power from a vehicle battery to the outside of a vehicle and a vehicle two-way charging device including the device, and more particularly, to such a device for supplying power from a vehicle battery to the outside of the vehicle and a vehicle two-way charging device including the device. , wherein, when the electric power accumulated in the vehicle's internal battery is supplied to an external load, it is possible to prevent hardware burnout while ensuring the robustness of the power supply. Background technique [0002] Generally, a plug-in hybrid vehicle or an electric vehicle has a large-capacity battery for storing power required to drive a motor of the vehicle, and may include a charging device for converting external power according to a battery voltage and thereby charging the battery . Traditional charging devices have unidirectional power flow to convert external power and provide it to...
