Title:
POWER SOURCE SYSTEM AND POWER SOURCE SYSTEM CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2022/252208
Kind Code:
A1
Abstract:
The present application provides a power source system, comprising: N power source modules and at least two adjustment units that are coupled to each other in one-to-one correspondence, wherein each of the adjustment units is connected to a controller; each of the power source modules is used for power conversion; the adjustment units are configured to obtain current working states of the corresponding power source modules, generate state signals and phase frequency signals, and send the state signals and the phase frequency signals to the controller; the controller generates an output power signal according to the state signals and the phase frequency signals; the adjustment units are further configured to obtain the output power signal, and regulate output power of the corresponding power source modules; and N is a positive integer greater than or equal to 2. In this way, ripple current of the power source system is reduced, and the efficiency and power density of the power source system can be improved at the same costs.
