目前大量使用的由可控硅等半导体器件构成的变流变频装置,虽能满足变流变频要求,但在复杂的变流变频装置中,其基本电路存在换流困难或波形畸变的问题。 本发明的目的是提供一种由转动的换向器和集电环同静态的可控开关元件结合及感性负载的若干组初级绕组与对应的次级绕组或对应的固有磁场来变流变频的方法。其具体
At present, a large number of variable frequency converter devices which are widely used, such as thyristors and other semiconductor devices, can meet the requirements of variable frequency and frequency conversion. However, in the complicated converter and inverter device, the basic circuit has problems of commutation problems or waveform distortion. It is an object of the present invention to provide a method of converting a plurality of primary windings combined with a static controllable switching element of a rotating collector and a static controllable switching element of an inductive load and corresponding secondary windings or a corresponding inherent magnetic field method. Its specific
