Questions & Step-by-Step Solutions
What is the main advantage of using a PWM (Pulse Width Modulation) technique in converters?
Step 1: Understand what PWM (Pulse Width Modulation) is. It is a method used to control the amount of power delivered to a device by varying the width of the pulses in a signal.
Step 2: Recognize that converters are devices that change electrical energy from one form to another, like from DC to AC or changing voltage levels.
Step 3: Learn that PWM helps in controlling the output voltage of converters by adjusting the duration of the 'on' and 'off' states of the signal.
Step 4: Realize that by controlling the output voltage, PWM can make the converter work more efficiently, meaning it uses less energy and produces less heat.
Step 5: Conclude that the main advantage of using PWM in converters is that it improves efficiency by reducing energy losses and controlling the output effectively.
