For rectangular pulses, duty cycle is pulse duration times repetition rate. Average power is peak power times duty cycle, and pulse energy is peak power times duration.
How it works in practice
These formulas assume the stated pulse shape and steady repetition. Real waveforms require integration or an appropriate measured envelope. Components need peak, energy, repetition and thermal limits that match the application. Average power alone is insufficient.
Example and interpretation
A 100 W, 10 microsecond pulse at 1 kHz has 1% duty cycle, 1 W average power and 1 millijoule per pulse.
Checks before use
- Specify waveform
- Calculate duration and repetition
- Calculate average and energy
- Check all component pulse limits
Important limit
Do not assume equal average power creates equal peak stress in different waveforms.
