Filed: 1985-07-30
Abstract: PURPOSE:To use many kinds of power supplies and to improve the reliability by providing the N-set of multi-output switching power supplies generating the M-kind of power supplies isolated electrically from a power supply from stations corresponding one by one to the N-set of stations while using the station power supply. CONSTITUTION:DC voltage V1 of equi-potential from smoothing circuits 8a-8c are combined by diodes 12a-12c for the purpose of multi-kind usage. Simiarly, DC voltages V2 of equi-potential from smoothing circuits 9a-9c are combined by diodes 13a-13c, DC voltages V3 of equi-potential from smoothing circuits 11a-11c are combined by diodes 14a-14c for the purpose of multiplexing usage. Thus, even if switching power supplies 40b, 40c corresponding to stations STN 10b, 10c are failed, when the switching supply 40a is normal, three kinds of power supplies V1-V3 are supplied from the power supply 40a. The voltage drop at the output terminal of the voltages V1, V2, V3 due to the fault of the switching power supplies 40b, 40c is prevented by the reverse current block ing operation by the diodes 12b, 12c, 13b, 13c, 14b, 14c.
