POWER SYSTEM AND POWER SYSTEM CONTROL METHOD

A power system includes N power modules and at least two adjustment units that are one-to-one coupled to the N power modules. Each adjustment unit is connected to a controller, and each power module is configured to perform power conversion. The adjustment unit is configured to: obtain a current working status of the corresponding power module, generate a status signal and a phase frequency signal, and send the status signal and the phase frequency signal to the controller. The controller generates an output power signal based on the status signal and the phase frequency signal. The adjustment unit is further configured to: obtain the output power signal, and adjust an output power of the corresponding power module based on the output power signal, where N is a positive integer greater than or equal to 2.
