    • Significantly increased torque is provided from a motor having a stator with a core and at least two three-phase windings wound on the core. The two windings are separated spatially by 30 electrical degrees. Power is provided to the two windings by two power supplies which each provide power at the same fundamental frequency and with a component at the third harmonic of the fundamental, with the power provided from one power supply shifted in time by 30° of the fundamental frequency with respect to the power provided by the other power supply. The additional third harmonic component reduces the effective peak flux density, allowing an increase in the fundamental component of flux to allow an increase in effective torque, with the third harmonic component also providing additional torque.

    • A brushless, synchronous machine is provided. A brushless, synchronous motor includes a rotor, a stator extending around at least a portion of the rotor and separated from the rotor by an air gap, a first stator winding, a second stator winding, a third stator winding, a drive circuit, a first rotor winding, a second rotor winding, and a diode bridge. The first stator winding, the second stator winding, and the third stator winding are mounted to the stator to generate square waves. The drive circuit is configured to provide a current to the first stator winding, the second stator winding, and the third stator winding, wherein the current includes an alternating current (AC) component and a direct current (DC) component. The first rotor winding is mounted to the rotor to form a plurality of third harmonic coils. The second rotor winding is mounted to the rotor. The generated square waves induce a voltage in the first rotor winding that is applied to the second rotor winding to create a brushless, synchronous motor. The diode bridge is mounted to the rotor to rectify the voltage induced in the first rotor winding and to apply the resulting DC voltage to the second rotor winding.

    • A dual bridge matrix converter has a line-side converter with controllable switches that receives AC power and provides unidirectional power to high and low DC link lines, and a load-side converter which receives the power from the DC link lines and provides AC power to output lines. A clamp circuit is connected across the DC link lines and includes a series connected diode and a capacitor. Negative DC link current will be conducted through the clamp diode to charge the clamp capacitor to avoid voltage spikes on the DC link lines. A controllable switch may be connected in parallel with the clamp diode and is turned on when the voltage across the clamp capacitor is above a threshold that is greater than the normal peak-to-peak AC input voltage. The switch is turned off when the voltage across the clamp capacitor is lower than the threshold voltage.

    • A drive system for a polyphase induction motor for extending the range of high frequency operation has two current source inverters connected to the polyphase motor to supply power to the motor. Motor speed and motor load are sensed and a circuit responsive to increasing motor speed and decreasing motor loads advances the firing pulses of one inverter while delaying the firing pulses of the other inverter. The advance in firing of one inverter and the delay in firing the other, reduces the effective current supplied to the motor while not decreasing the current available in each inverter for commutation.
