Document Type and Number:
Japanese Patent JP7188213
Kind Code:
B2
Abstract:
A power supply can be driven in parallel in a master-slave arrangement using fewer wires. Each power supply includes: input terminals; output terminals; a master terminal; a slave terminal; a switching power supply that switches an inputted voltage and executes one of a constant-voltage operation that outputs a DC voltage of a target voltage value and a constant-current operation that outputs a DC current of a target current value; an indicative voltage generator that generates a current detection signal indicating the current outputted from the output terminals, superimposes a bias voltage (>a threshold voltage), and outputs to the master terminal; and an operation switcher that compares a voltage applied to the slave terminal and the threshold voltage and outputs, based on the result, a control signal for switching to the constant-voltage operation or the constant-current operation, to the switching power supply.
