Latest Patents

Among his latest patents, Lai has developed a control circuit of a power converter and a reference voltage adjusting method. The control circuit includes a first sensing circuit, a reference voltage generation circuit, an error amplifying circuit, and a PWM circuit. The first sensing circuit, coupled to a first output circuit, provides a first current sensing signal. The reference voltage generation circuit, linked to the first sensing circuit, generates a reference voltage based on the first current sensing signal. The error amplifying circuit receives both the reference voltage and an output feedback voltage from the power converter to produce an error amplifying signal. The PWM circuit, positioned between the error amplifying circuit and the first output circuit, utilizes the error amplifying signal to control the first output circuit. Additionally, the reference voltage generation circuit adjusts the reference voltage according to the error amplifying signal.

Another notable patent by Lai is a control circuit of a power converter that includes a sensing circuit, a ramp signal generation circuit, and a PWM circuit. The sensing circuit provides a current sensing signal to the output circuit. The ramp signal generation circuit consists of a transient circuit and a signal generation circuit. The transient circuit generates a variable reference voltage based on the current sensing signal, while the signal generation circuit produces a ramp signal according to this variable reference voltage. The PWM circuit then generates a PWM signal for the output circuit based on the ramp signal. This innovative design allows for effective management of current sourcing and transient states.
