Abstract

This invention discloses a three-phase N switch linearity compound power conversion device serial with N source output devices, which compounds a linear unit and a switch filter unit of ripple supply to realize that the fidelity transfer power signals of source or emitter output device-like linear power amplifier either have the fine dynamic performance of load step force and the advantage of linear loads suiting resistance, induction and capacitive and the non-linear loads of some thyristors or casts away the shortcomings of low efficiency, heavy and large volume so as to get the performance better than switch amplifier, which provides a female parent for the coming-out or regeneration of three-phase boosters, starters, frequency conversion suppliers and super-low frequency motor converters and other special supplies of high performance harmonic-suppression.

Description

Technical field:

[0001] The invention belongs to the technical field of power electronics, and in particular relates to a three-phase N-wire switching linear composite power conversion device with N source output devices connected in series. Background technique:

[0002] The present invention is proposed on the basis of the prior invention patent "Tracking Power Active Filter" (Patent No.: 00112420.X). When the unit is combined, power devices need to be multiplied, and the cost increases. The "cost performance" of the three-phase system is difficult for enterprises to accept, thus limiting the development space of this original patented achievement. Invention content:

[0003] The purpose of the present invention is to overcome the problems existing in the prior art, and provide a three-phase N-wire switching linear composite power conversion device with N source followers connected in series.

[0004] The three-phase N-wire switching linear compound power conversion dev...
