A synchro (also known as selsyn and by other brand names) is, in effect, a transformer whose primary-to-secondary coupling may be varied by physically changing the relative orientation of the two windings. Synchros are often used for measuring the angle of a rotating machine such as an antenna platform. In its general physical construction, it is much like an electric motor. The primary winding of the transformer, fixed to the rotor, is excited by an alternating current, which by electromagnetic induction, causes currents to flow in three Y-connected secondary windings fixed at 120 degrees to each other on the stator. The relative magnitudes of secondary currents are measured and used to determine the angle of the rotor relative to the stator, or the currents can be used to directly drive a receiver synchro that will rotate in unison with the synchro transmitter. In the latter case, the whole device may be called a selsyn (a portmanteau of self and synchronizing).

There is provided a power transmission mechanism which is capable of employing one electric motor as a drive source for driving drive wheels and as a drive source for cranking an engine, thereby making it possible to reduce manufacturing costs of the hybrid vehicle, and preventing the motor from offering an extra rotational resistance to the engine when the drive wheels are being driven by the engine, thereby making it possible to enhance fuel economy. In the power transmission mechanism for transmitting the driving force from the engine and / or the electric motor to the drive wheels, when a synchro-clutch for the electric motor, driven by a switching actuator, connects the drive shaft of the electric motor and a driving drive shaft gear to each other, the electric motor is connected to the drive wheels via a meshing gear pair (driving drive shaft gear and driving output shaft gear), whereas when the synchro-clutch connects the drive shaft of the electric motor and a cranking drive shaft gear to each other, the electric motor is connected to the engine via a meshing gear pair (cranking drive shaft gear and cranking input shaft gear), the input shaft of the transmission, and a clutch.

The electronic switch may include a half-wave rectifier wired to the source terminal and the drain terminal of a MOSFET device, and a current monitor configured to monitor the drain-current flowing through the drain terminal. The current monitor sends a gate signal to the gate terminal such that the MOSFET is switched to its ON state when the drain-current exceeds a first threshold current and the MOSFET is switched to its OFF state when the drain-current falls below a second threshold current. Usefully, the synchro-rectifier may be incorporated into a full-wave rectifier.
