Title: The Innovations of Robert Chin
Introduction
Robert Chin is a notable inventor based in Vasteras, Sweden. He has made significant contributions to the field of electrical engineering, particularly in the development of advanced commutation circuits and electrical machines. With a total of 3 patents to his name, Chin's work reflects a commitment to enhancing efficiency and performance in electrical systems.
Latest Patents
One of Chin's latest patents is a high-efficiency commutation circuit. This innovative circuit includes a coil connected to an H bridge, which consists of four main switches for reversing polarity and controlling the resulting coil current. The circuit also features a voltage source designed to generate a bypass current, along with at least one auxiliary switch to manage this bypass current. This design effectively decreases the switch current through the main switches, allowing for the use of thyristors as main switches, which can turn off automatically when the current reaches zero. This advancement significantly reduces switching losses, even with various types of switches such as GTOs and IGBTs.
Another notable patent by Chin is for an electrical machine with circumferentially skewed rotor poles or stator coils. This invention includes a rotor featuring multiple pole sections, where adjacent poles within each section are spaced by a uniform pole pitch. The design allows for different pole pitches at either end of each pole section, which can also be applied to the stator coils of the electrical machine. This innovative approach enhances the performance and efficiency of electrical machines.
