Heric topology and off grid simulation/plecs 

Heric topology and off grid simulation model (plecs)
The inverter topology is: Heritage topology.
Simulation Description:
1. Support non unity power factor loads when off grid.
2. Support power factor adjustment during grid connection.
3. It has the ability to suppress common mode current (the common mode voltage is stable at Udc/2).
In addition, using PR single loop control with Sogipll
