Mention The Applications Of Pwm? |
|
Answer» PWM can be used to reduce the total amount of power DELIVERED to a load WITHOUT losses normally incurred when a power source is limited by resistive MEANS. This is because the average power delivered is PROPORTIONAL to the modulation duty cycle. With a sufficiently high modulation RATE, passive electronic filters can be used to smooth the pulse train and recover an average analog waveform.
