| Abstract: | Contactless mobile power is a device which supplies electrical power for moving equipments or other equipments with some special requirements for electrical power.Some useful ways to improve the efficiency of power transmission were studied.A circuit topology frame of inverter controlled by shift-phase full-bridge PWM,which could achieve zero-voltage and zero-current for switches,was discussed.This topology could noticeably boost the frequency of inverter and reduce switch loss.A new structure based on loosely coupled transformer was obtained for power transmission equipment of contactless mobile power.We also proposed the general model of loosely coupled transformer and calculating methods of its critical parameter calculation.Finally,we analyzed the efficiency of power transmission when the first coil and E type magnetic core were in different relative positions. |
