Techniques for converting power received from a power grid at a first voltage and outputting a signal at a second voltage are discussed herein. A power converter having a transformer having a 22.5 degree phase shift between currents output by a corresponding pair of secondary windings may be used to convert a first level of power to a second level of power. The transformer may output power from 30 secondary windings. The power inverter may output power having a total harmonic distortion of 5% and an efficiency of 96% or more. Further, power may be output by the transmit coil and received by a receive coil in a device, such as a vehicle, to wirelessly charge the vehicle.
本文讨论了用于转换以第一电压从电网接收的电力并以第二电压输出信号的技术。具有变压器的电力转换器可以用于将第一水平的电力转换为第二水平的电力,该变压器在由对应的次级绕组对输出的电流之间具有22.5度的相移。变压器可以从30个次级绕组输出电力。该电力逆变器可以输出具有5%的总谐波失真以及96%或更高的效率的电力。此外,电力可以由传送线圈输出并由设备(诸如车辆)中的接收线圈接收以对车辆进行无线充电。
