Multi-way sequential power-on circuit
First Claim
1. A multi-way sequential power-on circuit, operatively connectable to an external power source, for energizing a plurality of power units, comprising:
- switching means for selecting among the plurality of the power units a master power unit and for energizing the master power unit when the external power source is energized;
transmitting means for transmitting a start signal from the master power unit to remaining power units when the master power unit is energized to command the remaining power units to be energized;
receiving means in the remaining power units for receiving the start signal; and
energizing means for propagating the start signal along a bidirectional route beginning with the master power unit and in response to said receiving means receiving the start signal, to sequentially energize the remaining power units.

Abstract
In a power system having a plurality of power units which are supplied with an external power source and output a power source required for a load, multi-way sequential power-on operation is carried out by enabling two power units, designating as masters beforehand, to be turned on immediately when the external power source is turned on. The master, when turned on, transmits a start signal to two other power units, commanding the addressed power unit to be turned on. The addressed power unit, on receipt of a start signal from any of two other power units, turns on and transmits a start signal to two other power units, and thus propagating start signals on two routes beginning with two masters to sequentially turn on power units by twos at a time.
