摘要： A method is for a circuit for a motor comprising first and second phase windings. The method comprises receiving alternating current (AC) power from the first and second phase windings at a direct current (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 circuit for a motor comprises at least two phase windings forming one half of motor phase windings of the circuit and at least two other phase windings forming another half of the motor phase windings of the circuit. A direct current (DC) power supply receives alternating current (AC) power transferred from one or more of the motor phase windings and converts the AC power to DC power. A first stage power switch circuit comprising at least one power switch is connected between the at least two phase windings on the one half of the motor phase windings of the circuit and between the at least two other phase windings on the other half of the motor phase windings of the circuit. A second stage power switch circuit comprising at least one other power switch is connected between the one half of the motor phase windings of the circuit and the other half of the motor phase windings of the circuit, the at least one other power switch to receive AC power from one or more of the motor phase windings. At least one non-collapsing DC power supply component prevents the DC power supply from collapsing when the at least one power switch is on.

摘要： A phase windings circuit for a motor includes at least two phase windings forming one half of motor phase windings of the circuit and at least two other phase windings forming another half of the motor phase windings of the circuit. A direct current (DC) power supply is located at least approximately at a midpoint of the motor phase windings to receive alternating current (AC) power transferred from one or more of the phase windings and convert the AC power to DC power. A first stage power switch circuit comprises at least one power switch outside of the DC power supply and is electrically connected at least approximately at a midpoint between phase windings on each half of the circuit. A second stage power switch circuit comprises at least one other power switch outside of the DC power supply and is electrically connected at least approximately at the midpoint of the divided phase windings to receive AC power from the motor divided phase windings. A non-collapsing DC power supply component prevents the DC power supply from collapsing when the at least one power switch or the at least one other power switch is on and conducting.

摘要： A circuit includes phase windings to receive alternating current (AC) line voltage. The circuit has a direct current (DC) power supply, a power switch circuit comprising at least one power switch, and a control circuit to turn off the power switch circuit when a rotor associated with the circuit is in an identified rotor position, rotor magnet polarity, or speed relative to the AC line voltage. The circuit also has 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, power switch circuit, and control circuit may be at a midpoint of the phase windings.

摘要： A system and method for high speed switching comprises receiving voltage inputs at a bridge rectifier, generating a control signal from a transistor, and driving a gate of a field effect transistor (FET) via the control signal of the transistor, wherein a source of the FET is connected to a negative output of the bridge rectifier and a drain of the FET is connected to a positive output of the bridge rectifier through a load. The system and method further comprises limiting current flowing to the gate of the FET through first and second resistors and first and second diodes connecting the voltage inputs to the gate of the FET and limiting voltage to the gate of the FET below a maximum voltage rating of the FET by a Zener diode connected to the gate of the FET.

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 system is for a machine having an alternating current (AC) power source with a first side and a second side, one or more windings, an AC polarity detector, a Hall effect device, two or more pairs of power switches, and a motor controller. The motor controller determines which of the power switches to open or close to obtain a direction of current flow through the one or more windings based on signals from the AC polarity detector and the Hall effect device.
