BIDIRECTIONAL SERIES CONNECTED TOTEM POLE FOR SPLIT PHASE DCAC

DRIVE September 19, 2024
Source
A power stage circuit with multiple bidirectional AC to DC circuits for bidirectional charging is modified to connect the power stage converters in series for DC to AC applications. The power stage circuit can covert a DC input from a DC power source of a vehicle to an AC output for a power outlet of the vehicle. The power stage circuit uses two lines with a 120 VAC at the power outlet. Using a common neutral line, the AC to DC circuits are connected together to form a split phase power output, and the 120 VAC lines are 180 degrees out of phase to create a 240 VAC source at the power outlet.
