    摘要: A circuit for providing power factor correction includes a boost converter circuit with a boost inductance and a power factor correction switch and a control circuit. The control circuit provides a pulse width modulated signal to control the on time of a PFC switch, and also includes a power factor correction pulse width modulated device receiving as inputs a rectified AC input voltage, a DC bus voltage, a signal proportional to the current through the inductor and a reference current signal. The power factor correction pulse width modulated device also includes a pulse width modulated generator operable to provide the pulse width modulated signal to control the on time of the PFC circuit and a pulse width modulated blanking device operable to provide an enable/disable signal to disable the pulse width modulated generator when predetermined conditions are met.

    摘要: A power inverter control adjusts input power to track with output power to reduce energy handling requirements for an inverter DC bus. Input power to the power inverter circuit is measured and compared with a measurement of inverter output power. The comparison result is applied to a power factor correction circuit to adjust input power to track with output power, while obtaining a good power factor for the power inverter circuit. The energy requirements and ripple voltages or ripple currents on the DC bus are reduced, leading to a reduction in rating specifications for passive energy storage elements on the DC bus.

    摘要: A motor drive system control provides global closed loop feedback to cooperatively operate system components to adaptively reduce noise and provide noise cancellation feedback. An active EMI filter reduces differential and common mode noise on an input and provides a noise level indication to a system controller. Power switches in both a power converter and power inverter are cooperatively controlled with dynamic dv/dt control to reduce switching noise according to a profile specified by the controller. The dv/dt control is provided as an analog signal to a high voltage IC and codified as a pulse width for a level shifting circuit supplying control signals to the high voltage gate drive. A noise extraction circuit and technique obtain fast noise sampling to permit noise cancellation and adaptive noise reduction.
