ABSTRACT:
An inexpensive DC power source apparatus is provided which realizes a countermeasure against high frequency and redundant operation for improving reliability by using a simplified circuit construction to thereby reduce the number of parts. An input voltage follow type current controlled boosting chopper and a current feedback type self-running inverter are used in combination, and output voltage stabilization is accomplished by utilizing the voltage stabilizing function of the boosting chopper and current balance during parallel operation is accomplished by self-balance due to an impedance drop in the self-running inverter, thereby realizing the inexpensive power source apparatus in which the number of parts is reduced.
