Abstract

Methods and systems for controlling an output voltage of a resonant converter during a light load condition. One such method includes generating a normalised conduction time of the resonant converter that varies inversely with a switching frequency of the resonant converter by continuing to operate the resonant converter in a Pulse Frequency Modulation mode at a low switching frequency that is similar to the resonant frequency. The method also includes controlling a power level delivered to a secondary winding of a transformer positioned between a resonant tank and an output rectifier of the resonant converter by regulating the normalised conduction time, where the delivered power level is variable based on load conditions. The method further includes generating an output voltage using the output rectifier wherein the magnitude of the output voltage corresponds to the power level delivered to the secondary winding.

Abstract

A power-factor corrected AC/DC converter has three half-bridge legs, electrically coupled with each other in parallel, each leg having a pair of switches. Each switch of the pair is electrically coupled to the other in series via a respective node that is electrically coupled through an inductor to an AC line. The converter has a fourth half-bridge leg electrically coupled with the other legs to form an electrically parallel circuit. The fourth leg has a pair of switches electrically coupled to each other in series via a fourth node, which is selectively electrically coupleable to a neutral or a second AC line. The converter has a controller that operates the three legs as a 3-channel interleaved AC/DC boost converter and couples the fourth node to the neutral or second AC line if the input is single-phase, and as a 3-phase AC/DC boost converter if the input is three-phase.

A flat metal sheet is shaped, so that deformable ends of the sheet are incrementally rolled to form a split annulus approximating the outer circumference of a motor assembly. Once the split annulus is formed, the ends are elastically deformed to facilitate inserting the motor into a hollow portion of the split annulus. After the motor is inserted, the ends may be joined by welding one to the other. This type of housing secures the motor assembly through a crimping force applied by the housing. Alternately, the ends may be welded together and to the motor assembly itself, thereby forming a strong support structure between the housing and the motor assembly.
