    Abstract: A system or method for a VSD with an active converter including a controller, an inductor, an active converter, a DC link, and an inverter. The active converter is controlled to receive an input AC voltage and output a boosted DC voltage to a DC link, up to 850 VDC, the active converter using only low voltage semiconductor switches to provide the 850 VDC DC link voltage. The controller is configured to operate with a reactive input current magnitude equal to zero at a predetermined system load, and at system loads less than the predetermined system load, to introduce a reactive input current that results in a converter voltage having a magnitude less than the input voltage, wherein the vector sum of the input voltage and an inductor voltage is equal to the converter voltage.

    Abstract: A variable speed drive includes a converter connected to an AC power source, a DC link connected to the converter, and an inverter connected to the DC link. The inverter converts DC voltage into an output AC power having a variable voltage and frequency. The inverter includes at least one power electronics module and associated control circuitry; a heat sink in thermal communication with the power electronics module and in fluid communication with a manifold. The manifold includes a tubular member having at least one vertical member portion and at least one horizontal member portion in fluid communication. A plurality of ports conduct cooling fluid into and out of the manifold. A bracket attaches the manifold to a structural frame. Brackets are provided for attachment of power electronics modules to the manifold.
