Latest Patents

One of his latest patents is an "Apparatus for driving light emitting device with over-current and over-voltage protection." This apparatus includes a DC/DC converter that supplies an amplified driving voltage to the light-emitting part. It features a constant current circuit that controls the current flowing through the light-emitting part, along with a converter controller that manages both the DC/DC converter and the constant current circuit. Additionally, it incorporates a current sensor that converts the current flowing to the anode of the light-emitting part into a voltage. A feedback controller regulates the feedback current based on the voltage from the current sensor, while an optical coupling part transmits the feedback current as a feedback voltage. The main controller determines if an over-current is occurring and halts the operation of the converter controller when necessary.

Another notable patent is the "AC detection circuit for power supply." This circuit includes a rectifying part that rectifies an AC voltage, a voltage division part that divides the rectified voltage according to a preset ratio, and a voltage stabilization circuit that stabilizes the divided voltage. Furthermore, it features a first square wave generating part that compares the stabilized voltage with an internal reference voltage, generating a first square wave signal with a duty ratio based on the comparison results.
