Abstract

The differential frequency generator uses the interference between two voltages at different frequencies to produce a resulting voltage at half the difference between the frequencies of the component voltages. The generator comprises two alternators (a1, A2). Each alternator (A1, A2) has its own frequency and windings for each phase. Each phase winding is in series with the corresponding phase winding of the other alternator. The alternators (A1, A2) are connected to a transformer (21) and a bridge rectifier (22). The rectifier (22) gives a polyphased current whose frequency is equal to half the difference between the frequencies of the alternators.
