Patent number: 11906599Abstract: An earth leakage detecting device comprises following elements. A first end of coupling capacitor is connected to a current path of power storage connected to load in a state of being insulated from a ground. Voltage output unit generates a periodic voltage that changes periodically, and applies the periodic voltage to a second end of coupling capacitor via impedance element. Voltage measurer measures a voltage at a connection point between coupling capacitor and impedance element. Earth leakage determiner determines presence or absence of an earth leakage between the current path of power storage and the ground on the basis of the measured voltage. Voltage output unit has a preparation period for constantly outputting a potential between a high-side potential and a low-side potential of the periodic voltage before a measurement period for outputting the periodic voltage.Type: GrantFiled: June 15, 2020Date of Patent: February 20, 2024Assignee: SANYO Electric Co., Ltd.Inventors: Masato Nakayama, Tomonori Kunimitsu, Taisuke Hamada, Jun Asakura
