<P>PROBLEM TO BE SOLVED: To obtain a multi-parallel power supply unit having high noise resistance, stable operation, and quick control responses even if a number of power supply blocks are connected in parallel. <P>SOLUTION: A plurality of current-controlled power supply blocks 1a, 1b, ..., 1n are connected in parallel, and current command values are controlled by feeding back output voltages. High-frequency components of voltage feedback signals are transmitted via a local feedback path 18 provided for each of the power supply blocks 1a, 1b, ..., 1n. Low-frequency components of the voltage feedback signals are transmitted via a global feedback path 19 provided in the plurality of power supply blocks 1a, 1b, ..., 1n in common. <P>COPYRIGHT: (C)2010,JPO&INPIT |
