Abstract

A disconnecting circuit (SW1, RS, COM, CO) for a power converter (CON) supplies power to a load device (LO; 2). The disconnecting circuit (SW1, RS, COM, CO) comprises a switch (SW1) arranged in series with the power converter (CON) to disconnect a supply of power to the load device (LO, 2). A sense circuit (RS) supplies a sensed value indicating an operation mode of the load device (LO, 2). A controller (CO, COM) receives the sensed value to control the switch (SW1) to disconnect the supply of the power from the load device (LO, 2) when the sensed value drops below a reference level indicating a standby mode of the load device (LO, 2).
