High frequency modulation and demodulation multi-phase rectifier

This RF modem multi-phase rectifier device, three-phase AC for converting the three-phase alternating current input from the power source into a DC direct three-phase full-wave rectifier and (3), parallel with three sets of rings modulated wave power generator provided thereto vessel (7a) ~ (7c) and the three-phase multiple-turn wire high frequency multi-phase converter transformer (6) and a plurality of ring modulated wave demodulator provided corresponding to the number of phases and the auxiliary three-phase full-wave rectifier (4a) ~ comprising harmonic correcting circuit having (4c), wherein the DC output of the harmonic correction circuit connected in parallel with the DC output of the direct three-phase full-wave rectifier (3), equivalently viewed from the three-phase AC power supply side 6n phase (n is an integer of 3-7) and characterized in that it constitutes a polyphase full-wave rectifier circuit. Accordingly, smaller and lighter, low-noise, high-frequency modulation and demodulation multi-phase rectifier is provided to achieve high efficiency and low THD simultaneously.
