Abstract

See full text

An electronic circuit comprising an ACRF comprising an active component, an energy storage unit, an input port and an output port. The electronic circuit comprises a control unit to control the ACRF. A detector detects a short circuit at the input port or the absence of an energy supply at the input port. The control unit controls the ACRF to function as an ACRF if the detector detects a power supply connected to the input port or that there is no short circuit at the input port, and controls the ACRF to stop functioning as an ACRF and to discharge energy from its energy storage unit to its output port if the detector detects a short circuit at the input port or no power supply connected to the input port.
