Beschreibung
Zusammenfassung:	A vehicle battery output system includes: a DC-DC (direct current-direct current) converter configured to receive a direct current from a vehicle battery and convert the direct current into another direct current; a DC-AC (direct current-alternating current) inverter configured to convert the another direct current of the vehicle battery, converted by the DC-DC converter, into an alternating current; a controller configured to receive an input current, an output voltage, and a reference voltage and calculate a switching frequency modulation index to generate a control signal for controlling the DC-DC converter; and a DC (direct current) link disposed between the DC-DC converter and the DC-AC inverter and including a capacitor.
