Another system includes a boost converter including multiple switches coupled to a load and an AC voltage source. The switches are configured to provide charging current to the load in response to receiving switching commands. A D-Q control system configured to receive and delay an ia value, and issue switching commands based on the ia and delayed ia value is also included. A method includes performing a D-Q conversion to generate DC current including direct-phase and quadrature-phase current components, and issuing switching commands based on the current components.

An apparatus includes means for determining if current produced by the inverter is below/equal to a threshold amount, and means for altering voltage commands supplied to the inverter so that an AC motor is induced to draw additional reactive power. One method includes determining if a plurality of inductors are providing a threshold current amount, and inducing a motor to draw more reactive power if the current is below/equal to the threshold amount.
