By considering the energy consumption regulation window and the keyboard power consumption requirement, a primary current distribution strategy is formulated, and current distribution can be optimized according to the power consumption requirements of different areas, so that the energy utilization efficiency is improved.

By using multiple levels of policies, energy consumption and performance requirements can be met more accurately while maintaining a stable operating state. The setting of the intersection portions may ensure that different levels of policies are combined in some cases to better accommodate different operating conditions.
