Abstract:
 To investigate the influential factors of power devices on the dead-time of inverters,the effects
of voltage,current,and temperature on the switching time of the insulated-gate bipolar transistor ( IGBT)
were analyzed based on the semiconductor theory and the formula of dead-time. The regularity of the
three factors with the IGBT switching time was given and therefore the dead-time was obtained. Experiment
results using two-level half-bridge inverter unit shows that the dead-time increases approximately linearly
with the voltage ascending and the temperature ascending,but decreases with the current ascending,
following the composed rule of exponential and hyperbola. In addition,the occurrence of bridge
shoot through is in accordance with the calculation of dead-time,which proves the accuracy of the theoretical
analysis. Finally, the obtained conclusion can be important references for the accurate setup of
dead-time and the optimization of dead-time compensation algorithm in electrical power converters in
practical applications.
