    摘要: A pulse-width modulation (PWM) inverter controller compensates for harmonics in the output current provided by a PWM inverter to permanent magnet (PM) motor. The PWM inverter controller includes a field-oriented controller (FOC) that monitors output currents provided by the PWM inverter to the PM motor and employs the monitored output currents in a current loop feedback that generates control signals. A harmonic compensator transforms monitored phase currents into rectangular waveforms having magnitudes modified based on detected harmonics within the monitored phase currents to generate compensation signals. The compensation signals generated by the harmonic compensator are summed with the control signals generated by the FOC to generate compensated control signals. A PWM signal generator generates PWM signals for controlling the PWM inverter based on the compensated control signals.

    摘要: An active rectifier controller controls operation of an active rectifier employed in a power conversion system that supplies a direct current (DC) output to an inverter that converts the DC output to an AC output supplied to an AC motor. The active rectifier controller includes a field-oriented control (FOC) controller that monitors an alternating current (AC) input currents provided to the active rectifier, the DC output provided to the inverter, and speed of the AC motor. The FOC controller selects a reference DC output value based on the speed of the AC motor and compares the monitored DC output to the reference DC output as part of the FOC control algorithm used to generate control signals. A PWM signal generator generates PWM signals for controlling the active rectifier based on the control signals.

    摘要: A power converter includes a PWM active rectifier and controller that minimize harmonic ripple currents on the DC link during an engine start mode (first stage) in which power is provided to an AC starter motor. The PWM active rectifier and controller also minimize harmonic currents on AC input lines during a second stage (active filter mode). The power converter also includes a PWM inverter and corresponding inverter controller that controls the performance of the AC starter motor during the first stage based on mode selection input received. The power converter system further includes pre-charge circuitry that charges a DC link capacitor located within the power converter system to a desired level prior to providing the power converter system with AC power.

    摘要: A power management and distribution (PMAD) system includes a main DC bus, an auxiliary DC bus, a power converter, one or more hybrid solid-state circuit breakers, and a controller. The power converter converts power from the main DC bus to provide a regulated output to the auxiliary bus. Each hybrid SSCB includes a main switch connected between the main DC bus and a load and an auxiliary switch connected between the auxiliary DC bus and the load. The controller selectively turns the main switch and the auxiliary switch On/Off to selectively supply power from the main DC bus and/or the auxiliary DC bus to the load, and to selectively regulate the voltage on the auxiliary DC bus.
