Galvanic isolator for high voltage isolation communication device, has receiver circuit connected to receiving coil that generates signal similar to input signal based on pulses corresponding to rising and falling edges of input signal

摘要

The isolator has transmitter coil (23) and receiving coil (24) that are arranged on the surfaces of electrically insulating substrate (52). A transmitter circuit connected to transmitter coil comprises detector that detects rising and falling edges of input signal. Pulse generators generate several pulses based on detection of rising and falling edges of input signal. Receiver circuit connected to receiving coil generates signal that is similar to input signal based on generated pulses.
