Claim of US Patent No. 10,251,227

1. A clocked electronic energy converter havingan electronic switching element,
at least two electrical energy storage devices,
a first terminal for connecting to an electrical energy source,
a second terminal for connecting to an electrical energy sink,
a clock generator for controlling the electronic switching element during switching operation,
an input terminal for a first signal adjusting a power to be transmitted by the energy converter,
a first timer connected to the clock generator and to the input terminal, for providing a second signal representing a switch-on time, the clock generator being designed to adjust the power to be transmitted by the energy converter in a first power range,
wherein the power to be transmitted by the energy converter in a first power range is configured to be adjusted by the switch-on time of the electronic switching element, and
a second timer connected to the clock generator and the input terminal for providing a third signal representing a supplemental switch-off time in a second power range in which the power to be transmitted by the energy converter is less than in the first power range, the clock generator being designed to adjust the power to be transmitted by the energy converter in the second power range,
wherein the power to be transmitted by the energy converter in the second power range is configured to be adjusted by a combination of the second and the third signal,
wherein the third signal is constant.
