Abstract:
1. A device for providing electric power to a load, comprising two switch members (Z wherein each switch member comprises a switchable member and a flywheel diode connected in parallel with the switchable member; a monitoring circuit for monitoring a current (I) through said inductor and a bridge voltage (E) at said bridge point; a control circuit for providing control signals to the switch members for turning said switchable members ON and OFF; the control circuit, when said current is positive, being adapted to turn the first switch member OFF when said current exceeds a predetermined control value (I a hysteresis circuit having an upper hysteresis limit (I said upper hysteresis limit (I wherein when the control value (I wherein the sum of said upper hysteresis limit (I wherein E is a bridge voltage L is said inductor.
