Synchronization of a control signal with grid voltage on the basis of zero crossing is not convenient in digital control systems because of disturbances causing multi-crossing of zero and additional hardware required for detection. A new method of synchronization to AC networks for phase-controlled rectifiers or for front-end rectifiers is presented in this article. All theoretical dependencies are also included.
