摘要： 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.

At least one galvanically isolating element is arranged between the output of the inverter and the input of the rectifier, and a capacitance is coupled between the output terminals. The inverter converts a partial DC voltage, being smaller than the full DC input voltage, across a capacitance between the second one of the input terminals and the second one of the output terminals.

摘要： A digital isolation circuit includes an encode circuit, a planar magnetic circuit, and a decode circuit. The encode circuit receives an input signal and divides the input signal into a first signal pulse and a second signal pulse. The planar magnetic circuit is coupled to an output of the encode circuit. The planar magnetic circuit includes a primary winding, a secondary winding and a magnetic core. The primary winding is magnetically coupled to the secondary winding through the magnetic core to generate an isolated output signal in response to the pair of signal pulses. The decode circuit receives the isolated output signal from the secondary winding to generate an output signal substantially identical to input signal. A method of digitally isolating a square wave input signal from an output signal using the digital isolation circuit is also disclosed.

摘要： Solid state light sources are compatible with AC phase-cut dimmers. The light sources may have switching mode power supplies having primary and secondary sides that are in first and second circuit parts that are electrically isolated from one another. Information regarding a waveform of input electrical power is extracted in the first circuit part and passed to a controller in the second circuit part by way of a galvanic isolator. Additional isolated paths may be provided to provide bi-directional exchange of information between the first and second circuit parts and/or to provide for the exchange of additional information relevant to control. The signal path from the first side to the second side may have a low latency.
