摘要： A bidirectional AC power converter, having a front-end comprising parallel sets of three switches in series, which connects multi-phase AC to coupling transformer through a first set of tank circuits, for synchronously bidirectionally converting electrical power between the multi-phase AC and a DC potential, and for converting electrical power between the DC potential to a bipolar electrical signal at a switching frequency, controlled such that two of each parallel set of three switches in series are soft-switched and the other switch is semi-soft switched; the coupling transformer being configured to pass the bipolar electrical power at the switching frequency through a second set of the tank circuits to a synchronous converter, which in turn transfers the electrical power to a secondary system at a frequency different from the switching frequency.

摘要： A method and apparatus that performs AC to DC power conversions without creating significant 50 or 60 Hz harmonic currents and voltage distortions on the AC power source conductors thus minimizing the need for ancillary harmonic filtering of 50 or 60 Hz harmonics. The method and apparatus is embodied in a circuit that first performs balanced modulation on a 50 Hz or 60 Hz power voltage converting it to a higher frequency, then subsequently passing the resulting wave through a step-up transformer to produce a higher voltage wave and finally rectifying and filtering the higher voltage wave to produce a DC voltage. The higher frequency waveform may be pulse width modulated to effect output DC voltage regulation. The circuit is typically comprised of semiconductor switches, pulse control circuits, transformers, filter capacitors, filter inductors, semiconductor diode rectifiers, DC voltage measurement circuits and other components.

摘要： Apparatus and associated methods involve a controllable supply adapted for controlling switch phasing and pulse width to substantially equalize power in adjacent quadrants of a sinusoidal source voltage waveform to regulate reactive power drawn from the source. In an illustrative example, the supply may, in some embodiments, deliver power to a load at a level responsive to a commanded input signal. In some examples, the power supplied to the load may be adjusted according to the command input signal to a selected value within an operating range. In some examples, the operating range may include a portion or all of 0 to 100% of rated load. Various embodiments may be adapted to supply unipolar or bipolar load excitation. In some embodiments, high power factor may be maintained over a substantial range of commanded power to the load. Certain embodiments may enhance supply efficiency by capturing and recycling inductive load energy.

摘要： Methods and apparatus for providing and controlling power to at least some types of loads. In one example, a controlled predetermined power is provided to a load without requiring any feedback information from the load (i.e., without monitoring a load voltage and/or load current). In another example, a “feed-forward” power driver for an LED-based light source combines the functionality of a DC-DC converter and a light source controller, and is configured to control the intensity of light generated by the light source based on modulating the average power delivered to the light source in a given time period, without monitoring and/or regulating the voltage or current provided to the light source. In various examples, significantly streamlined circuits having fewer components, higher overall power efficiencies, and smaller space requirements are realized. Based on various power driver configurations, lighting apparatus incorporating one or more power drivers for one or more LED-based loads may be implemented, and multiple such lighting apparatus may be coupled together to form a lighting network in which operating power is efficiently provided throughout the network.

摘要： Power factor correction control methods and apparatus based on knowing in advance some information relating to anticipated load conditions (e.g., a desired power to be provided to a load). Based on “feeding-forward” known information about anticipated load conditions, power factor correction control loop response is significantly improved, particularly in situations in which the load power traverses a wide range in a short time period (e.g., load full off to load full on, or vice versa). As a result of improved control loop stability, smaller circuit components may be employed based on more predictable expectations for signal values, thereby reducing the cost and/or size of the implemented circuits. In one example, a processor controls both a feed-forward power factor correction apparatus and a feed-forward power driver for an LED-based light source to provide an efficient source of radiation using significantly streamlined circuits having fewer components and smaller space requirements.
