WebMar 23, 2024 · When controlling motors or heaters we use the duty cycle to dictate the power. If our PWM controller outputs a voltage of 12 volts DC, then a 50% duty cycle would provide the equivalent of 6 volts DC to power the load. Figure 2. PWM signal showing various duty cycles at a 250 Hz carrier frequency. PWM for DC Motor Speed Control WebWe found, as it's highlighted there and we found that the output voltage equals the input voltage divided by 1 minus that duty cycle. In a simple example where we have an input voltage of 100 volts. In order to get 200 volts at the output, you'd need to have a 50 percent duty cycle so D equals 0.5.
