| Popis: | Efficiency is an important index for high power wireless power transfer system. Combined with the characteristic that the normal traction demand of the modern tram can be satisfied when the input DC voltage of the traction inverter is in a certain range, an efficiency optimization method of WPT system with inductor/capacitor/capacitor (LCC) compensation structure used for the modern tram power supply is proposed by adjusting the phase shifting angle of the primary inverter according to the traction power. Without increasing the hardware circuit, the proposed method can maintain the transfer efficiency as high as possible under different operating conditions. Theoretical analysis and simulation verify the effectiveness of the proposed method. |
