Abstract:
A DC/DC converter (1) comprises: two input terminals (2, 3) for a DC input voltage (U E ); two output terminals (4, 5) for a DC output voltage (U A ); an inverter (7) converting a DC voltage into an AC voltage; and a rectifier (10) converting an AC voltage from the inverter into a DC voltage between a first one of the input terminals (3) and a first one of the output terminals (5). At least one galvanically isolating element is arranged between the output (8) of the inverter (7) and the input (9) of the rectifier (10), and a capacity is operative between the output terminals (4, 5). The inverter (7) converts a partial DC voltage being smaller than the full DC input voltage (U E ) and dropping over a capacity (6) which is operative between the second one of the input terminals (2) and the second one of the output terminals (4).

Abstract:
Control circuits are provided for regulating an output voltage of a switched mode power supply having a variable input voltage and at least one power switch. The control circuits are operable to generate a comparison voltage based on the output voltage of the switched mode power supply and a duty cycle of a control signal provided to the at least one power switch, determine a reference voltage based on whether the generated comparison voltage falls within one of a plurality of voltage ranges, and adjust the duty cycle of the control signal provided to the at least one power switch of the switched mode power supply as a function of the determined reference voltage and the output voltage. Each voltage range is associated with a different reference voltage. Switched mode power supplies including the control circuits and methods implemented by the control circuits are also disclosed.

Abstract:
A power supply includes two or more input waveforms being shaped or selected so that after being separately level-shifted and rectified, their additive combination results in a DC output waveform with substantially no ripple. The power supply may comprise a waveform generator, a level conversion stage for step up or down conversion, a rectification stage, and a combiner. The waveform generator may generate complementary waveforms, preferably identical but phase offset from each other, such that after the complementary waveforms are level-converted, rectified and additively combined their sum will be constant, thus requiring no or minimal smoothing for generation of a DC output waveform. The level conversion may be carried out using transformers or switched capacitor circuits. Feedback from the DC output waveform may be used to adjust the characteristics of the input waveforms.
