MITSUBISHI Application Note Prep. ELECTRIC CORPORATION Rev. Apr. A.3 Protective Function (M81012FP, M63914FP) （１） Voltage Overshot Control Function （OV1） Generally, the output voltage of a boost type active filter will rise greatly at a light load. OV1 is designed to restrain the overshot of the output voltage. When the voltage exceeds the defined value by about 20V, IGBT gate input will be blocked so that the further voltage rise can be restrained.
