Abstract: AC motor driving system and driving method thereof are provided. The driving system and method are capable of increasing power factor, adjusting waveform of the DC ripple voltage for increasing driving efficiency. The driving system is basically constructed by connecting three circuits. The first circuit is a three-phase full wave rectifying circuit and is used to transfer commercial electricity to a first DC voltage. Then, the second circuit is used to transfer the first DC voltage to a second DC voltage that ripples voltage thereof having a semi-sinusoidal waveform. The third circuit is an AC driving circuit, and receives the second AC voltage for driving the AC motor. Thereby, the driving efficiency can be increased. The capacitance used in the present disclosure has low capacitance value, thus the power factor can be increased, and usage time of the AC motor driving apparatus can also be increased.

Abstract: An example power management arrangement includes a motor controller configured to communicate power to a motor drive bridge to drive a motor. The motor controller is configurable to selectively receive power from each of a first power supply and a second power supply. The voltage of the power from the first power supply is different than a voltage of the power from the second power supply. An example power adjusting method includes receiving power at a motor controller, adjusting a voltage of the received power using the motor controller, communicating the power with the adjusted voltage from the motor controller to a motor drive bridge to drive a motor.

Abstract: In some aspects, an actuation system includes an electrical positioning driver and an electrically-driven actuator. A voltage boost converter in the electrical positioning driver receives an input voltage. The voltage boost converter passes the input voltage to a voltage bus in the electrical positioning driver. The voltage on the voltage bus is converted to an actuator power signal that controls the electrically-driven actuator. The voltage boost converter boosts the voltage on the voltage bus to control a mechanical output performance of the electrically-driven actuator.

Abstract: An electrical controller for electric rotating machines is provided. A control system for electric rotating machines transmits a controlled quantity of current to or from different windings of the electric rotating machine at any given time. Furthermore, the amplitude of the current is independently variable of the timing and duration of the transmission of the current to or from the windings. This allows increased control of the electric rotating machine and facilitates the operation of the electric motor at high mechanical and/or electrical speeds.
