Abstract: The output voltage generated by permanent magnet generator (PMG) is regulated by controlling a buck/boost voltage applied to selected sub-coils within the PMG. The PMG includes a number of stator coils that are each divided into a number of sub-coils. A buck/boost voltage source generates a buck/boost voltage, and a controller connected to monitor the output voltage generated by the PMG selectively applies the buck/boost voltage to selected sub-coils based on the monitored output voltage. In this way, the controller is able to regulate the output voltage by selectively controlling the buck/boost voltage applied to the selected sub-coils.

Abstract: A variable speed drive with a boost converter is provided for a chiller system driven by an induction motor. The boost converter can be a diode or thyristor rectifier followed by a boost DC/DC converter or a three-phase pulse width modulated boost converter. The boost converter provides a boosted voltage to the DC link, which results in a boosted voltage being applied to the induction motor by the inverter of the variable speed drive.

Abstract: A voltage sensor (101) is connected to output terminals (P, N) of a booster. The voltage sensor (101) detects a boosted voltage, and outputs the detected voltage to a first drive controller (102). The first drive controller (102) outputs a control signal to a variable resistor (22) indicating a gate resistance obtained on the basis of the boosted voltage. The variable resistor (22) is controlled to have the specified gate resistance in response to the received control signal.
