Abstract
A system and method of detecting phase angle in an inverter is provided. A shunt resistor is coupled to a controller which is part of an inverter circuit and a phase angle may be directly derived from the detected voltage across the shunt resistor. The detected shunt voltage may be used to adjust the power delivery from the inverter to the load.
