  • Dead-time control method for power electronics converters and a circuit for the application of this method
    Patent number: 11757376
    Abstract: A dead time control method (100) comprising the steps of: converting the DC link voltage, output current and output voltage to digital values with an ADC (Analog to Digital converter) (102); calculating the hysteresis band for adaptive hysteresis current control using the values read by the ADC and updating the band value via recalculating it at each sampling time (103); calculating the IrefH and IrefL values using the hysteresis band and Iref (103a); generating the PWM signal by hysteresis current control (104), generating two auxiliary control signals as VP, VN (105); in the region where VP=1 and VN=0, applying of the drive signal of T1 without setting dead time wherein T1 is the conduction duration of an upper switch, and not applying the drive signal of T2 wherein T2 is the turn off duration of said upper switch and is the conduction duration of a lower switch (106).
