transformer inductance
1.Familiar PWM, PFM control chip, IGBT, power component, high-frequency transformer, inductance and so on MOSFET and so on magnetic elements.
2.With reference to the new design of electric locomotive, the article clarifies the effects of transformer leakage inductance on the power sup ply characteristics (power factor, current harmonic component) of electric locomotive. It also derives the concerning computation formula and carries out computation and analysis by using computer.
3.Uses:Packing of high tension electrical equipment,expoxy pouring packing material,plastic pacing material,dry type transformer,high tension mutual inductance equipment,insulator.
4.The faculties in Zhejiang University have begun the research of solid states power switch and fault current limiting technology. They provide a novel solid stats fault current limiting technology, which possesses flexible control mode. The experimental prototypes of 380V/200A transformer coupling three phase bridge type solid state fault current limiter (SSFCL) and 10Kv/500A transformer coupling three phase bridge type SSFCL with bypass inductance have been developed successfully.
5.The coupled inductor and the forward transformer transfer the power together in which, the coupled inductor in flyback BDC, and the leakage inductance in phase shifted BDC vice verse.
6.Besides, there is also some alternatives, such as an inductance conversion using differential transformer and space curve deformeter, and variable resistance pressure transmitter.
7.The functions and effect of inductance and capacitance in the circuit of single and double transformer on the current wavcform and ripple factor have been studicd and tested systematically in this paper and it is proved that this power supply without any forms of filter circuit in the sccondary eide of transformer can obtain direct currcnt with stability, no currcnt zero and low ripple factor to satisfy complctely the rcquircmcnt of CO2 lascr when it is conncctcd a single-phase nctwork service.
