Latest Patents
One of Xinmin Yi's latest patents is titled "Circuits and methods for controlling power converters including transformers." This invention involves a circuit that includes a transformer and a controller. The transformer operates in multiple switching cycles, which consist of a charging period and a discharging period. During the charging period, the transformer is powered by the input voltage, causing the current in the primary winding to increase. Conversely, during the discharging period, the transformer discharges to power the load, resulting in a decrease in the current flowing through the secondary winding. The controller plays a crucial role by generating control signals to regulate both the input voltage and the output current flowing through the load.
Another significant patent by Yi is "Circuits and methods for controlling a light source." This invention features a driving circuit that includes a frequency controller and a switch module. The frequency controller receives a dimming signal to control the light source's brightness. It generates a second dimming signal with a frequency outside predetermined ranges when the first dimming signal falls within those ranges. The switch module alternates between on and off states to achieve the desired brightness based on the generated dimming signals.
