Title:
DC-TO-DC CONVERTER
Document Type and Number:
Japanese Patent JP2001238434
Kind Code:
A
Abstract:
To solve the problem due to the voltage of a power supply line being lowered by a rush current produced, when a power supply is closed and other apparatuses connected to the same power supply line malfunction.
A current limiting unit is inserted in series into an input side of a DC-DC converter unit and the current limiting unit is made to operate for a prescribed time, immediately after a power supply is closed. Further, the operation of the current limiting unit is discontinued, before a current is outputted by the DC/DC converter unit. As a rush current can be minimized, and influence upon other apparatuses connected to the same power supply line can be avoided.
