This control circuit is ideal for the accurate control of DC motors as well as other applications like lighting levels and small heaters etc. The circuit converts a DC voltage into series of pulses, such that the pulse duration is directly proportion to the value of the DC voltage. The great advantage of such a [...]
This uses the LM324, a 14-pin DIL IC containing four individual op-amps and running off a single-rail power supply. The sawtooth is generated with two of them (U1A and U1B), configured as a Schmitt Trigger and Miller Integrator, and a third (U1C) is used as a comparator to compare the sawtooth with the reference voltage [...]
