A switchable bidirectional power converter can comprise an interleaved bridge configuration. A multi-phase grid connection to a half-bridge multi-phase switching bank can comprise a first switching half-bridge leg. A single-phase grid connection to a full-bridge single-phase switching bank can comprise the half-bridge multi-phase switching bank interleaved with the full-bridge single-phase switching bank. The full-bridge single-phase switching bank can comprise the first switching half-bridge leg and a second switching half-bridge leg. A capacitor switch can be configured to switch at least two power factor correction capacitors between a parallel connection and a serial connection. The serial connection also includes a center tapping connection to the second switching half-bridge leg. Such a power converter can be used in a bidirectional on-board charger. Ultra-wide range voltages can be handled bidirectionally.

A control apparatus for a conveying system includes: a control module configured to control a power converter coupled to a motor, and a modification module. The modification module is configured to: estimate a size parameter of an item conveyed by the motor, determine if a hold command is received; and if a hold command is received, modify one or more parameters of the control module based on the estimated size parameter of the item to thereby hold a rotor of the motor at a rotor hold position.

A resonant converter device comprising a selectable primary winding comprising a plurality of circuit legs, the selectable primary winding comprising one or more of a tapped primary winding or a plurality of switchable primary windings. At least one secondary winding coupled to the selectable primary winding to form a resonant transformer. At least one resonant inductor coupled to at least one of the plurality of circuit legs. A plurality of resonant capacitors, each circuit leg comprising at least a respective one of the plurality of resonant capacitors, and at least a second resonant capacitor of the plurality of resonant capacitors coupled within the second circuit leg. And, one or more switching devices connected to the resonant transformer and configured to selectively vary a resonant impedance of the resonant converter device when a voltage inputted to the resonant converter device varies.
