In order to calculate the duty cycle, we need to first find the frequency or period of the variable signal. This can be found with multiple methods, but the initial approach can be to measure the pulse width of the transmitted signal. To do this with an unknown signal, we can connect t...

2) IC_GetMeasurement returns captured value of FTM counter at the time edge happens, if edge detect mode is selected ( rising, falling or both edges) or difference of 2 captured value if signal measurement mode is selected (period between 2 rising/falling edges or...
Calculate the duty cycle using the following formula: Duty Cycle = 100 * (Time on ) / (Time on + Time off) Following the example leads to a duty cycle of: Duty Cycle = (30 minutes) / (30 + 10 minutes) = 30/40 = 75 % Erroneous calculations can have significant effects, which ca...
Now that we know all the parameters of the struct we can do some math to determine the duty cycle. The setup would look something like the image below: So to determine the duty cycle in this example you would take TAxCCR1/TAxCCR0 = 3200/32000...
The pulse width and period of the PWM wave can be calculated by recording the counter value of the signal along the changing moment, so as to calculate the duty cycle. The program is shown below. When actually invoking, Digital IO can be replaced with the module IO.Back to top ...
Points to note are: - Horsepower is at the engine (count a drivetrain loss of 30% if you calculate based on wheel horsepower) - Injector duty cycle is 80% - Fuel pressure is 3bar (43.5psi) Petrol, Turbocharged or Supercharged Petrol, NA ...
The first step is to calculate the duty cycle at the minimum input voltage: D = 1 - (Vin(min)×η) / Vout Where: Vin(min)= minimum input voltage Vout= output voltage η = efficiency (e.g., 80%) Calculating Ripple Current
In a no load condition, you can use the motor’s KV value to estimate the motor’s speed based on the voltage delivered. As discussed in our article on how to calculate motor KV, we can replace Back EMF with input voltage in this equation to estimate the rotation speed of our electric...
The duty cycle can be used to estimate the apparent analog voltage that a pulse width modulation signal will provide. The diagram below shows the effect of duty cycle on the apparent voltage: To calculate the duty cycle required for a specific apparent voltage: ...
