用于栅极驱动隔离信号传输的巨磁阻抗传感器

A proof-of-concept of the use of a giant-magneto-impedance (GMI) sensor for the realization of signal transmission under high isolation voltage is presented. This technology, which has never been used for gate driver units before, can potentially provide low coupling capacitance (<;1 pF) and high insulation voltage capability up to 40 kV for a gap of 1 mm. The signal information is carried by a ma...
