Abstract: A braking energy recovery system (50) for an electric motor (62) comprises first regulator (52), energy storage device (54), second regulator (56), sensor (60), and controller (58). The first regulator (52) outputs a DC link voltage to the energy storage device (54). The second regulator (56) couples to the energy storage device and outputs a motor drive signal to the electric motor (62). The sensor (60) senses an operating characteristic of the electric motor. The controller (58) outputs to the first regulator an energy management signal (74) that comprises a time variant signal as a function of (i) motor speed and/or (ii) back EMF determined via the sensed characteristic, whereby the first regulator dynamically regulates the DC link voltage to maintain substantially constant an energy balance that comprises a sum of (a) rotational and/or linear kinetic energy of the electric motor and (b) energy stored in the energy storage device.

Abstract: A low profile transformer comprises a support member for supporting a coil winding, a first elongated conductive tape forming at least one conductor having lead terminals formed integral therewith formed into a first coil of multiple turns, a second elongated conductive tape having lead terminals formed integral therewith forming at least one conductor formed into a second coil of at least one turn interleaved with the first coil, and each terminal lead of each of the tapes extending from the support member and having a portion disposed at a base of the transformer for engagement and surface bonding to a PC board.
