This application discloses a phase alignment circuit and a method of a receive end, and a receive end. The receive end is located on an electric vehicle. The phase alignment circuit includes a phase measurement circuit and a controller. The controller is configured to: use, as an actual phase shift angle, a result obtained by subtracting a phase difference from a preset phase shift angle, and control a phase of a bridge arm voltage of a rectifier to lag behind the phase of the input current fundamental component by the actual phase shift angle. The controller outputs a drive signal for a controllable switching transistor of the rectifier by using the actual phase shift angle. Because a lagging phase caused due to filtering is compensated for, precision of synchronization between the bridge arm voltage and the input current can be increased.
