バータ起動同期回路。[Claims for Utility Model Registration] A circuit that controls starting and stopping of each DC/DC converter by the on or off state of a switch provided corresponding to each DC/DC converter operated in parallel. In the startup synchronization circuit provided corresponding to each of the DC/DC converters, a startup/stop signal sending circuit for sending out a startup/stop signal indicating the on state or disconnection state of the corresponding switch; a plurality of input terminals into which start/stop signals indicating the on or off state of each of the other earlier switches are input; and the start/stop signal output from the start/stop signal sending circuit is connected to the a control circuit that indicates a state and starts the corresponding DC/DC converter when all the start/stop signals input to the plurality of input terminals indicate the on state of the switch. DC/DC converter startup synchronization circuit.
