摘要
A voltage balance control method applicable to a three-phase DC-AC inverter is provided, the voltage balance control method including: multiplying, by a first multiplier, an actual value of a line capacitance voltage by a sine function to generate a first voltage; capturing, by a first filter, a DC part of the first voltage to generate an error DC component; subtracting, by a first subtractor, the error DC component from a target voltage amplitude to generate a second voltage; adjusting, by a first proportional-integral controller, the second voltage to generate an amplitude error compensation value; and adding, by an adder, the amplitude error compensation value with the target voltage amplitude to generate an amplitude reference value. A voltage balance control device applicable to a three-phase DC-AC inverter is also provided.
