Engineering Contradiction Analysis
1Speed
If the output circuits remain continuously operational to ensure immediate power availability, then the power supply readiness is improved, but the power consumption increases and service life decreases
Solution Approach 1:
The patent implements dynamic control of output circuits by the main control circuit, which monitors load conditions in real-time and adjusts circuit states accordingly. When no load is detected for a preset time period, the control circuit automatically turns off the output circuits to save energy. When load is detected, the circuits are immediately activated, achieving both energy savings and quick power availability.
2Loss of energy
If the output circuits are turned off during no-load conditions to reduce power consumption, then the power efficiency is improved, but the response time to provide power may increase
Solution Approach 1:
The main control circuit continuously monitors load conditions in advance and maintains system readiness. When a load is detected on the output circuits, the control circuit proactively activates the circuits before complete power delivery is needed, ensuring minimal response time. The preset time period for turning off circuits is optimized to balance energy savings with rapid response capability.
3Productivity
If continuous monitoring of load conditions is implemented to enable automatic circuit control, then the power management efficiency is improved, but the device complexity increases
Solution Approach 1:
The main control circuit performs multiple functions: it monitors load conditions on output circuits, determines when to turn circuits on or off based on preset time periods, manages power distribution, and controls indicator lights. By consolidating these functions into a single control circuit, the patent achieves efficient power management without proportionally increasing device complexity.

AI summary
An energy storage power supply includes a drive circuit of the energy storage power supply. The drive circuit of an energy storage power supply includes a charging control circuit, a first direct current output circuit, an alternating current output circuit and a main control circuit. The main control circuit can detect the load condition of the first direct current output circuit and the alternating current output circuit, and then the main control circuit controls the first direct current output circuit and the alternating current output circuit to be off. Thus, the problem of high power consumption when the alternating current output circuit and the first direct current output circuit in the energy storage power supply are in the no-load state is solved.
