Patent ID: 8063512

Claim:
A power-saving power supply apparatus with battery module applied to a load device, the power-saving power supply apparatus with battery module capable of converting an inputted AC power into an outputted power and comprising: a Triac switch electrically connected to the inputted AC power; a Triac driver electrically connected to the Triac switch; a power microprocessor connected to the Triac driver; and a battery module electrically connected to the power microprocessor, wherein when the power-saving power supply apparatus with battery module is idle or in low workload, the power microprocessor sends a low-potential switch signal to the Triac driver to turn off the Triac switch and thus shut off the inputted AC power, so that the battery module provides power to the power microprocessor to detect whether the power-saving power supply apparatus with battery module is not idle or in low workload; when the power-saving power supply apparatus with battery module is not idle or not in low workload detected by the power microprocessor, the power microprocessor sends a high-potential switch signal to the Triac driver to turn on the Triac switch and thus the inputted AC power is converted into the outputted power, so that the battery module does not provide power to the power microprocessor.
