Latest Patents

Yunfei Liu holds a patent for a "Detecting method for an operating state of a power supply and a detecting apparatus." This invention provides a method for detecting the operating state of a power supply, which includes a primary circuit, a transformer, and a secondary circuit. The secondary circuit is equipped with a secondary current detecting unit, a temperature detecting unit, and a secondary controlling unit. The process begins with the secondary current detecting unit measuring the current value of the secondary circuit. The secondary controlling unit then compares this current value with a preset threshold. If the current value is less than or equal to the threshold, the temperature detecting unit measures the temperature of the power supply. Based on this temperature value, the secondary controlling unit determines the operating state of the power supply.
