Patent ID: 8487482

Claim:
A circuit for controlling the power supply of a consumer, said circuit comprising: a current source with two inductances connected in series for providing a power supply for a consumer, wherein the circuit includes a negative branch and a positive branch, a potentially separately actuated first switch connected in parallel with the series connection consisting of the current source and the inductances, in which through opening and closing of the first switch the power is transmitted to the consumer in the form of square wave current pulses, a series connection arranged in parallel with the first switch, which series connection consists of a potentially separately actuated second switch in the negative branch, the consumer and a potentially separately actuated third switch in the positive branch, wherein the circuit includes a first load with a load voltage connected in parallel with the second switch, or the second switch includes a breakdown voltage comprising a load combined with the second switch, and wherein the circuit includes a second load with a load voltage connected in parallel with the third switch, or the third switch includes a breakdown voltage comprising a load combined with the third switch, and wherein the second switch and the third switch are opened and closed in anti-phase manner to the first switch.
