Title: Weixiang Jin: Innovator in Voltage Conversion and Control Methods
Introduction
Weixiang Jin is a notable inventor based in Hangzhou, China. He has made significant contributions to the field of electrical engineering, particularly in voltage conversion and control methods. With a total of three patents to his name, Jin's work has the potential to enhance the efficiency of power systems.
Latest Patents
Weixiang Jin's latest patents include a bleeder current control circuit and a voltage converting circuit. The bleeder current control method involves several steps, including the transmission of a post-bridge input signal to the power system. A shaping circuit then processes this signal into a bleeder current reference signal, which is inversely correlated with the initial input signal. By acquiring a current sampling signal and comparing it with the reference signal, an error signal is generated. This allows for the control of the current sampling signal, ensuring that it aligns with the waveform of the bleeder current reference signal. This method aims to provide a reliable sine wave envelope signal to the power system, thereby reducing losses caused by bleeder current.
The second patent focuses on a non-isolating AC-DC voltage converting system that utilizes two voltage converters. The first converter activates a power transistor when the bus voltage is at its lowest, providing an interim voltage that is lower than the bus voltage. The second converter then takes this interim voltage to deliver the output voltage for the AC-DC voltage converting system.
