An electromechanical transducer apparatus is disclosed and includes a housing. A static portion is substantially immobilized within the housing and includes a magnetic flux generator for generating magnetic flux, a pair of pole pieces for coupling magnetic flux through at least one of a first magnetic circuit and a second magnetic circuit, and a coil disposed to electromagnetically interact with one of the magnetic circuits. The static portion is thermally coupled to the housing via a low thermal resistance path to permit removal of heat. A movable portion includes first and second closing pieces separated from the pole pieces by first and second gaps. The closing pieces are mechanically coupled and supported for reciprocating motion about an equilibrium position which varies the gaps to cause a variation in magnetic reluctance in each of the first and second magnetic circuits.

One or more variable configuration controller (VCC) systems may produce various combinations of series or parallel couplings of coils, winding or inductive elements of an electric machine such as a generator and/or electric motor. The VCC systems include a plurality of bridge rectifiers, and a first number of switches operated to selectively couple respective pairs of coils in series from parallel on an AC side of the bridge rectifiers. The bridge rectifiers provide for automatic electrical isolation of coils on occurrence of open circuit, low voltage or short circuit conditions. A second number of switches with different performance characteristics (e.g., speed, loss) than the first number of switches may be coupled in parallel with respective ones of the first number of switches. Power factor correction may be used.
