Circuit topology for bi-directional energy transfer has error amplifier that provides control signal for MOSFET gate connections, compares output voltage actual values with desired value

摘要

The arrangement has two lines, each with a MOSFET (20,22), whereby the MOSFETs are connected with their gate and source connections with a resistance connected between the connected source and gate connections. An error amplifier (28) that provides a control signal for the gate connections compares an actual value of each output voltage (U1,U2) with a desired value for a reference voltage.
