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.

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.

The invention relates to an electric machine (2) comprising a rotor (10), a stator (20) with a circumferentially arranged stator winding (22) that consists of an electrically conductive material, and a housing (30) with a first and a second opening (32, 34) extending in a circumferential direction. A ventilator (40) is arranged on the end-face side of the rotor (10), said ventilator being connected to the rotor (10) in a rotationally fixed manner and having radially extending vanes (42). A cooling medium (46) is aspirated from the ventilator (40) via the first opening (32), blown out via the second opening (34) and swiftly conveyed past, at least at sub-regions of the stator winding (22), between said first and second opening (32,34).

A resonant, bi-directional, DC to DC voltage converter with loss-less (soft) switching having regulated output and capable of converting power between two, high-potential and low-potential DC voltage sources. The converter's semiconductor and magnetic components provide both, output regulation and soft switching in both (step-down and step-up) directions of power conversion which reduces total component count, cost and volume and enhances power conversion efficiency.

Abrégé

The invention relates to a method for determining the electric angular speed of a rotor of an induction motor, wherein electric power supplied to phases of a stator of the induction motor affects the rotor, comprising the steps of: switching off the electric power supply to the phases of the stator during a particular period of time, picking-up signals corresponding to voltages at the stator phases within the particular period of time, and determining the electric angular speed of the rotor based on the picked-up signals.

Abrégé

A method for securing a motor housing to a motor assembly is provided. One application of the method creates a motor housing to secure and protect a motor assembly. 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.
