Abstract
Disclosed is a circuit for shifting a fixed ground level to a floating ground level in a motor drive system, including a floating ground high level line, a floating ground output level line, a floating ground low level line, a normal input level line, and a normal ground line that are used for characterizing an application detail. The circuit includes a controlled switching current source, a first upper current rectifier, a second upper current rectifier, a lower current rectifier, and an amplifying and shaping circuit that are integrated on a same substrate.
