摘要： A multi-phase active filter includes a group of power cells electrically connected in a three-phase configuration, a precharging circuit, and a controller that controls the voltage delivered to the plurality of power cells. Each power cell includes an inverter having a pair of direct current (DC) terminals, at least one capacitor electrically connected in parallel with the inverter, and an energy dissipating circuit that is electrically connected in parallel with the inverter. The energy dissipating circuit of each power cell self-regulates DC voltage within the cell.

摘要： A power supply apparatus and method for supplying direct current power to low and medium voltage DC loads wherein a multi-phase transformer having multiple secondary windings provides multi-phase power to multiple power cells, each of which have a single DC output and are controllable by a modulation controller. The primary and secondary windings in the power transformer may be star- or mesh-connected; the secondary windings may be shifted in phase. Because the power cells can be connected in series, the maximum output voltage for each cell may be less than the maximum line-to-line voltage. The power cell output can have variable DC voltage and current which can be controlled using pulse-width modulation techniques. AC input power is converted to DC output power for each power output line. Output power modulation can be produced by interdigitating a selected number of carrier signals so that harmonic components reflected back to the input are attenuated.

摘要： A high frequency ultrasonic system for sonically removing particles from substrates or wafers held in a carrier or carriers in a tank of liquid, such as DI water. A frame encompasses the tank and supports the transducer housing at an angle with respect to the tank bottom and also provides for horizontal movement between the sides of the tank. A transducer housing supports at least one transducer within the transducer housing. The transducer housing can be supported and moved at an angle with respect to the tank bottom.

摘要： This invention is an improvement to a multi-level, multi-phase power supply. Typically, in such power supplies, each of the phases has one or more power cells providing a pulse width modulated output. In such a configuration, when the transition of the pulse width modulated outputs of corresponding power cells in different phases occurs simultaneously, a double step in voltage is observed on the output of the power cell. This invention is an improvement over the prior art wherein the transitions of the outputs of the power cells are controlled to avoid simultaneous transitions.
