Generator with circuitry for controlling power generation based on rotational speed

摘要

A full-wave-rectifying-circuit is composed of six diodes and six transistors inversely connected in parallel with the diodes. A phase-control-circuit has three magnetic sensors each of which corresponds to one of the phase-windings and positioned so as to lag by an electric angle of 90 DEG to provide digital signals which lag an electric at an angle of 60 DEG behind the induced-phase-signal. The six transistors are driven by the digital signals to form controlled AC voltages which lag behind the induced line voltages by an electric angle 60 DEG so that the alternator increases the output power without increase of the body size.
