Abstract
A voltage compensating method is applied to a converter for converting a DC voltage into an AC voltage. The converter includes a first switch module, a second switch module, and an inductor. In a first dead time period, detect a first current value related to the inductor. According to the first current value, calculate a second current value and a third current value related to the inductor. According to polarities of the first, second and third current values, determine an output mode of the converter indicating a voltage compensation model after the first dead time period. According to the voltage compensation model, the first current value, and the second current value or the third current value, calculate a voltage compensation value. In a second dead time period, adjust a switching time for the first switch module and the second switch module according to the voltage compensation value.
