摘要: An improved transformer-less electronic isolating transformer is obtained with an output subcircuit that outputs a controlled current rather than voltage. Specifically, the hybrid comprises drive receives ac signal and creates corresponding passed to line supports two way communication. The not only converts applied voltage but includes means for effecting gain. Signals arriving from are directly near-end echo circuit also responsive subcircuit. Both input of isolated opto-isolators employ photodiodes in their photo-voltaic mode.
