Title: Innovations by Chiping Sun
Introduction
Chiping Sun is a notable inventor based in Boulder, CO (US), recognized for his contributions to power generation technology. With a total of five patents to his name, he has made significant advancements in engine-driven systems.
Latest Patents
One of his latest patents is for a small engine-driven generator. This power conversion system includes an engine coupled to drive an alternator, a rectifier circuit, and an ignition controller. The alternator features a stator and a rotor that work together to provide current to the rectifier circuit. The rectifier circuit outputs power with a specific voltage, while the ignition controller supplies energy to the engine's spark plug. If the voltage exceeds a predetermined limit, the ignition controller reduces energy to the spark plug to decrease engine drive. The system also includes an engine throttle controller and a winding control circuit that selectively couples windings to the rectifier circuit, facilitating predetermined output power with low engine RPM for noise abatement.
Another significant patent focuses on throttle control for small engines and other applications. In this system, the throttle of an engine operating under heavy load is controlled to prevent over-speeding or stalling. Successive control signals sent to a throttle actuator are inhibited until a predetermined time has elapsed since the last adjustment. This ensures that the engine has sufficient time to respond to each incremental adjustment. The throttle actuator may be a stepper motor or a solenoid, with the processor monitoring engine speed and generator load to determine necessary adjustments.
