Latest Patents

One of Zhi-Hui Ding's latest patents is a light driving circuit. This circuit includes a first and second illuminant unit, a power conversion unit, a first and second switching unit, and a first control unit. The power conversion unit receives an input voltage and converts it into an output voltage. The first switching unit is coupled to the first illuminant unit, allowing it to emit light and generate a first output current when activated. Similarly, the second switching unit is linked to the second illuminant unit, which emits light and generates a second output current when turned on. The first control unit manages the operation of both switching units based on the output currents.

Another notable patent is a light regulating apparatus with feed forward compensation and its corresponding method. This apparatus consists of a converter, a load circuit, and a controller. The converter outputs a load current signal based on a controlling signal, which drives the load circuit. The controller generates the control signal and includes an error calculation unit, a regulation unit, a feed forward compensation unit, and an addition unit. The error calculation unit produces a first error signal based on a reference current signal and a feedback signal, while the regulation unit generates a regulating signal. The feed forward compensation unit creates a compensation signal, and the addition unit combines these signals to produce the final control signal.
