Latest Patents

Luo's latest patents include a protection circuit designed for use in lighting circuits. This innovative protection circuit comprises a voltage clamping circuit and a discharge circuit connected to the ground. The discharge circuit features a gas discharge tube component and a controllable voltage triggering circuit with a specific triggering threshold. This design ensures that a hi-pot test voltage is insufficient to trigger the voltage triggering circuit, allowing for low current conduction. Conversely, a surge test voltage is capable of breaking down the voltage triggering circuit, resulting in a low voltage drop and a large current flow.

Another significant patent involves a MOSFET circuit, which is particularly useful in tapped linear drivers and surge protection methods. This circuit clamps the MOSFET gate voltage when the source voltage exceeds a threshold level, especially during voltage surge events. The gate is held at a voltage relative to the source, effectively turning off the first MOSFET during surge events while allowing normal operation otherwise. A threshold circuit is integrated between the gate and a reference voltage, ensuring that when the source voltage exceeds a certain level, it conducts a unidirectional circuit component to protect the MOSFET.
