Abstract: A motor assembly for driving a pump or rotary device features a power plane with a circular geometry to be mounted inside a space envelope having a similar circular geometry formed on an end-plate between an inner hub portion and a peripheral portion that extends circumferentially around the space envelope of the end-plate. The power plane is a multi-layer circuit board or assembly having: a power layer with higher temperature power modules for providing power to a motor, a control layer with lower temperature control electronics modules for controlling the power provided to the motor, and a thermal barrier and printed circuit board layer between the power layer and the control layer that provides electrical connection paths between the power modules of the power plane and the control electronics modules of the control layer, and also provides insulation between the power layer and the control layer.

Abstract: This invention relates to the field of matrix converters and more specifically to the field of matrix converters comprising bidirectional switches. There is proposed a concept of providing a minimum transistor switching period for any given transistor in the matrix converter. Such a minimum transistor switching period may be induced by introducing a delay into a commutation sequence that is typically used to switch an output from a first input to a second input.
