PURPOSE: A power supply for a vehicle is provided to generate and supply direct current power individually and independently by a first voltage generator and a second or third voltage generator and to continuously supply more stable voltage by using a first half-wave rectifier and controlling output voltage of the second or third voltage generator. CONSTITUTION: A power supply for a vehicle comprises a first half-wave rectifier(3), a first voltage generator(16,5,15), and a second voltage generator(2,8,9,91). The first half-wave rectifier half-wave rectifies three phase AC voltage from a generator for vehicle into positive polarity three phase half-wave voltage. The first voltage generator transforms the rectified three phase half-wave voltage and rectifies the transformed three phase half-wave voltage into constant DC voltage, and then applies the rectified voltage to a first load(15). The second voltage generator rectifies the three phase half-wave voltage into a constant DC voltage to apply the same to a second load(13), and then rectifies AC voltage induced from the vehicle generator into positive DC voltage to apply the same to the second load.
