摘要： A method for a circuit for a motor comprising first and second phase windings. The method comprises receiving AC power from the first and second phase windings at a DC power supply and converting the AC power to DC power and receiving AC power from the first and second phase windings by at least one power switch between the first and second phase windings and switching the AC power by the at least one power switch. The method includes preventing the DC power supply from collapsing, by a first component connected to the DC power supply, when the at least one power switch is on during a first portion of an AC cycle and preventing the DC power supply from collapsing, by a second component connected to the DC power supply, when the at least one power switch is on during a second portion of the AC cycle.

摘要： A method is for a machine having an alternating current (AC) power source with a first side (L1) and a second side (L2), two or more pairs of power switches, and one or more windings. The method comprises closing one pair of power switches by a control circuit to cause current to flow from a first side of the AC power source, through the one or more windings, and to the second side of the AC power source and closing another pair of power switches by the control circuit to cause current to flow from the second side of the AC power source, through the one or more windings, and to the first side of the AC power source.

摘要： A multispeed alternating current (AC) machine circuit is for an AC power source having a first side and a second side. The AC machine circuit includes two or more pairs of power switches, one or more windings, and a control circuit to close one pair of power switches to cause current to flow from a first side of the AC power source, through the one or more windings, to the second side of the AC power source and to close the other pair of power switches to cause current to flow from the second side of the AC power source, through the one or more windings, to the first side of the AC power source.

摘要： A circuit includes motor phase windings that are divided, a direct current (DC) power supply between the divided motor phase windings, a power switch circuit comprising at least one power switch, the at least one power switch being between the divided motor phase windings. The circuit also includes a first non-collapsing DC power supply component to prevent the DC power supply from collapsing when the at least one power switch is on during a first portion of a cycle and a second non-collapsing DC power supply component to prevent the DC power supply from collapsing when the at least one power switch is on during a second portion of the cycle.

摘要： A circuit includes phase windings, a direct current (DC) power supply, and a power switch circuit. The power switch circuit includes at least one power switch. The circuit also includes a control circuit to control the power switch circuit. The control circuit includes a logic control shut off circuit to shut off the control circuit when the motor is at synchronous speed. The circuit also includes at least one non-collapsing DC power supply component to prevent the DC power supply from collapsing when the at least one power switch is on and conducting during at least a portion of a cycle. One or more of the DC power supply and power switch circuit may be at a midpoint of the phase windings.
