When multiple PWM converters are connected in series (or in parallel) in a power electronics circuit, it is appropriate to run all converters at the same frequency but with certain phase shift among ...

This example is similar to the Motor example 01, but this time it spins from zero to max speed using a custom PWM frequency of 40kHz (40000Hz), what improves the motor performance, reduces noise and ...

Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

because the frequency has been set low enough for the human eye to detect. This flicker is easiest to see when the LED is moving with respect to the eye and when it is between about 20% - 60% ...
