Title: Innovations by Bin Ma in Charge Control Technology
Introduction
Bin Ma is an accomplished inventor based in Dongguan, China. He has made significant contributions to the field of charge control technology, holding 2 patents that showcase his innovative approach to electrical engineering.
Latest Patents
One of his latest patents is a "Wake-up circuit for charge controller, on-board charger, and new energy vehicle." This invention includes a first-stage charging circuit and a second-stage charging circuit. The first-stage charging circuit features a first capacitor that charges and outputs a first charging voltage to the second-stage charging circuit when it receives a high-level signal. Conversely, when it receives a low-level signal, it discharges the first capacitor. The second-stage charging circuit, which includes a second capacitor, utilizes the first charging voltage to charge the second capacitor and output a wake-up signal to the charge controller. This design enhances the scenario coverage of the wake-up circuit, ensuring high applicability.
Another notable patent is a "Converter and on-board charger." This invention aims to prevent short-circuit faults while inhibiting surge impacts. It comprises a power factor correction (PFC) circuit, a surge protection circuit, and a switch circuit. The PFC circuit converts alternating current into direct current and vice versa, effectively managing power flow and enhancing the reliability of the system.
