Latest Patents

Among his latest patents, Jayabalan has developed an active damping circuit that includes a peak current limiter, a drain source voltage limiter, a turn-on driver, a resistor shunt circuit, and a peak current sensor. This circuit is designed to detect a rising edge of an input voltage from a phase cut dimmer by identifying a higher peak current. The peak current sensor plays a crucial role in driving the collector voltage of a second transistor low, which subsequently lowers the gate voltage of a first transistor, allowing it to function as a damping resistor. When the peak current sensor detects a decrease in peak current, the circuit is prepared for the next edge of the input voltage.

Another significant patent involves an active damping circuit and system that comprises various components, including resistors, transistors, capacitors, and a microcontroller. This design enhances the functionality of the circuit by ensuring that it operates efficiently and effectively in response to varying input conditions.
