Title:
電源の動作不良状態を検出するためのシステムおよび方法
Document Type and Number:
Japanese Patent JP5198062
Kind Code:
B2
Abstract:
A system and a method for detecting an operational fault condition in a power supply are provided. The power supply has a controller operably coupled to first and second switches. The first and second switches are connected in series between a voltage source and a ground node, wherein a first electrical node is electrically coupled between the first and second switches. The first electrical node is further coupled to a first end of an inductor. The controller is configured to induce the first and second switches to apply voltage pulses to the first electrical node. The method includes monitoring a voltage at the first electrical node to determine a number of voltage pulses being applied to the first electrical node over a predetermined time interval. The method further includes determining when a first operational fault condition has occurred when the number of voltage pulses being applied to the first electrical node over the predetermined time interval is less than or equal to a predetermined number of voltage pulses.
