I need to know how can I increase the duty cycle of a pwm.
Thank you very much :)

A duty cycle in a PWM (Pulse Width Modulation) is the percentage of time that a signal is ON compared to the total time of the signal. It is typically represented as a percentage or a decimal value between 0 and 1.
To increase the duty cycle of a PWM, you can either increase the ON time of the signal or decrease the OFF time of the signal. This can be achieved by adjusting the pulse width or frequency of the PWM signal.
Increasing the duty cycle in a PWM allows for a longer ON time of the signal, which can result in a higher average voltage or current output. This can be useful in various applications such as motor speed control or LED brightness control.
One potential drawback of increasing the duty cycle in a PWM is that it can increase the power dissipation and heat generation in the circuit. This can cause damage to components if not properly controlled. Additionally, increasing the duty cycle too much can result in signal distortion and potentially affect the accuracy of the output.
To calculate the new duty cycle after increasing it, you can use the formula: Duty Cycle = (ON Time / Total Time) x 100%. Alternatively, if you know the previous duty cycle and the desired increase, you can simply add the increase to the previous duty cycle. For example, if the previous duty cycle was 30% and you want to increase it by 10%, the new duty cycle would be 40%.
