19.1.3.1 PWM with Dither
Depiction of 2 kHz PWM with 100 Hz 40% dither.
Lower waveform is voltage, upper waveform is
current through a typical inductance.
19.1.3.2 PWM with Dither
Single cycle of 2 kHz PWM with 100 Hz 40% dither.
Note: PWM voltage duty cycle is changing value +/- 20% from
commanded value at a rate of 100 Hz.
19.1.3.3 PWM with Dither
PWM with dither illustrating duty cycle
62% (42% + 20%)
19.1.3.4 PWM with Dither
PWM with dither illustrating duty cycle
22% (42% - 20%)
