From November 6th to 9th, the 2020 4th International Conference on High Voltage Direct Current (HVDC 2020) was successfully held in Xi'an. Fu Junyin, general manager of Bronze Technologies, and Chen Hengxing, deputy general manager, were invited to the event. At the meeting, Bronze Technologies demonstrated the latest high-voltage and high-power gate driver products, and introduced the magnetic ring energy-capture press-packed IGBT driver technology, drumming up passionate interest among attendees.



As a leader in the power device driver industry in China, Bronze Technologies offers a wide range of driver products. The high-voltage, high-power gate drivers exhibited at the conference feature high integration, intelligence and reliability. Based on Bronze Technologies proprietary ASIC chips, the drivers feature compact design, low power consumption, convenient debugging, multiple applications, and cost effectiveness, and can be securely and reliably drive IGBT and SiC power devices. The inductive-magnetic-coupling-powered press-pack IGBT gate driver can be used in high voltage power transmission and marine power applications. By controlling the current flowing through the silicone cable, the primary side current source supplies power to the secondary side driver unit. Compared to traditional solutions of using multi-level isolation or bulky isolation transformers for insulation purpose, the inductive-magnetic-coupling-powered press-pack IGBT gate driver solution can simplify the system and reduce the design cost.
