    摘要: A power supply apparatus comprises power supplies (12, 14) that share the power requirements of a common lead (20) approximately equally. Either of the power supplies (12, 14) can act as the «master» while the other power supply acts as the «slave». The arrangement utilises an integrating differential error amplifier (54), an inverting amplifier (56), and a noninverting amplifier (58) which are electrically connected between the common load (20) and the power supplies (12, 14) to detect any difference in the output current of the power supplies (12, 14) due to a difference in output voltage, and to correct the difference by increasing the output voltage of the power supply having the lower output voltage until the difference is eliminated. In this manner, either power supply (12, 14) can act as the «master» while the other power supply acts as the «slave».
