Latest Patents
One of his latest inventions is the "Front-stage voltage-adjustment inverter." This invention discloses a front-stage voltage-adjustment inverter that includes a front-stage voltage-adjustment unit, a duty cycle modulation unit, a half-bridge driving unit, and a transformer unit. The front-stage voltage-adjustment unit receives input power, a dimming signal, and a feedback signal. It varies the voltage of the input power according to the dimming signal and performs feedback adjustments based on the feedback signal. Importantly, the cycle signal generated by the duty cycle modulation unit remains constant, allowing the half-bridge driving unit to operate in a zero-voltage switching state. This innovation reduces switching loss and extends the service life of loads and electronic components.
Another significant patent is the "Inverter with adjustable resonance gain." This invention comprises a PWM unit, a switch unit, a resonance unit, a transformer, a feedback unit, and a frequency control unit. The switch unit draws DC power from a power source, while the PWM unit generates a working cycle signal to drive the switch unit, converting DC power into pulse power. The resonance unit then transforms this pulse power into driving power for the transformer, which outputs the final power. Notably, when the resonance unit operates at a starting frequency and a working frequency above the starting voltage, it produces a starting voltage gain and a working voltage gain. The starting voltage gain is larger, enabling the output power to initiate lamp tube sets smoothly.
