Advantages and Disadvantages of PWM
Given Below are Advantages and Disadvantages of PWM :
Advantages
- PWM technology keeps LEDs from overheating while preserving their brightness.
- PWM technology responds quickly and with accuracy.
- A high input power factor is provided by the PWM technique.
- Motors may provide their full torque even at lower speeds thanks to the PWM technology
Disadvantages
- The significant switching losses are a result of the high PWM frequency.
- Radio Frequency Interference is caused by it (RFI).
Pulse Width Modulation (PWM)
In Electronic Engineering, Pulse Width Modulation, or PWM, is a commonly used technique for effectively controlling the power supplied to electrical devices. In order to attain a desired average voltage or power level, the principle of pulse width modulation (PWM) is used for a periodic signal, which is usually a square wave.
A key component of pulse width modulation (PWM) is the duty cycle, which is defined as the ratio of the pulse width to the whole time period. An increase in the duty cycle translates into an increase in average power output. Basically, PWM is used to obtain analog signals from digital services- for instance, the microcontrollers and it represents the amplitude of an analog signal input signal.
