Solution Approach 1:

The power source is divided into separate voltage source unit and current source unit, each independently controlling voltage and current respectively. This segmentation allows high-speed current control without requiring high-speed voltage modulation, thereby maintaining signal accuracy while achieving power savings through independent optimization of each source.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention dynamically adjusts the operational parameters of the voltage source and current source independently based on signal conditions. The current source can respond rapidly to signal changes while the voltage source provides stable bias, creating a dynamic system that maintains efficiency without causing distortion.

2Loss of energy

If multiple operational voltage sources are used to improve efficiency, then power consumption is reduced, but switching between sources causes slowness and signal distortion

Engineering Contradiction:

Core Design Contradiction:

Loss of energyVSSpeed

Solution Approach 1:

The invention merges the functions of multiple power sources into a unified system where voltage source and current source work simultaneously rather than switching between them. This eliminates the switching delays and distortions associated with multiple separate voltage sources while maintaining the efficiency benefits through coordinated operation.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The current source unit serves multiple functions: it provides operational current during high signal levels and compensates for voltage source limitations during low signal levels. This multi-functionality eliminates the need for switching between multiple voltage sources, improving both speed and efficiency.

AI summary

The solution controls electric operational power to be fed to an amplifier. The control can be carried out, for instance, in accordance with a predetermined signal. The operational power is fed to the amplifier with a voltage source unit and a current source unit, and the operational voltage that the voltage source unit feeds to the amplifier is controlled. The current source unit feeds at least some of the operational electric current of the amplifier.
