Web2 jul. 2024 · Dead time setting is an 8 bit value. As a result it can be set between 0-255. This setting configures dead time duration in respect to the timer input clock. Note that this clock is before the “prescaler”. In our example, timer running frequency is 1 MHz but input frequency is 8 MHz. Dead time is determined from this clock. WebA short circuit will result if the two IGBTs are turned on at the same time. As a result, by using a PWM wave with dead time, the upper and lower devices will not turn on at the same time. That is, if one device is switched on and then turned off, the other can be turned on after a period of inactivity. Ⅰ. What is a dead band?
