Latest Patents

Deshui Yu holds a patent for a "Current Ripple Canceling LED Driver." This invention focuses on a light-emitting diode (LED) driver that effectively cancels current ripple. The design includes an input current source that contains a current ripple, with the LED load connected to the drain of a power switch. The source of the power switch is linked to a current sensing resistor, while the gate of the power switch is connected to the output of an operational amplifier. This operational amplifier compares the voltage signal across the current sensing resistor with a dynamic reference voltage, which is adjusted according to the gate or drain voltage of the power switch. As a result, the LED load current is controlled to be a nearly no ripple DC current.
