2.4 Working Principle
2.4.1 Circuit Diagram
The Smart PCS implements rectication and inversion through a three-phase
three-level converter. The rectied output is converted from three-phase AC power
to DC power and then stored in the energy storage system (ESS). The inverted
output is
ltered to a three-phase AC voltage, which is then isolated and boosted
by a three-phase transformer and fed into the power grid.
