Abstract: A controller and an interleaved switching method for a converter for a polyphase connected inductive load including a method for operating: at least a first drive circuit and a second drive circuit in parallel, each connected to one or more phases of the polyphase connected inductive load.

Abstract: Methods and systems are provided for an onboard charging system of an electric vehicle.

Abstract: A charging station for an electric vehicle, wherein the electric vehicle and the charging station each have couplers and & communication modules. The couplers are releasably coupled for transfer of energy & the communication modules communicate the charging data. The charging station further include: an interface connects with an external source of electrical energy; a control module provides control signals and a switching module is responsive to the control signals for selectively connecting the second coupler and the interface for allowing the transfer of energy between the couplers; and operating in: a first mode to allow provide at least one of a regulated the coupler current or and the coupler voltage to be regulated; or a second mode to allow the provide an unregulated coupler current or and the coupler voltage to be unregulated.

Abstract: The invention is to a controller for a DC electric motor having a first drive circuit and a second drive circuit that operate in a first state and a second state wherein, in the first state, circuits are connected with terminals input and are responsive to the control signals for receiving a load current and selectively energising winding to create torque in motor. In the second state, circuit is disconnected from terminal such that: circuit is able to be responsive to current for generating a first DC charging current to batteries; and circuit is able to connect with a terminal and be responsive to a second DC charging current for selectively directing an energizing current through winding.
