Questions & Step-by-Step Solutions
In a buck converter, what happens to the output voltage when the duty cycle is increased?
Step 1: Understand what a buck converter is. It is a device that converts a higher input voltage to a lower output voltage.
Step 2: Learn about the duty cycle. The duty cycle is the percentage of time the switch in the buck converter is 'on' compared to the total time of one cycle.
Step 3: Realize that when the duty cycle increases, the switch is 'on' for a longer period of time during each cycle.
Step 4: Know that when the switch is 'on', energy is transferred to the output, which increases the output voltage.
Step 5: Conclude that if the duty cycle is increased, the output voltage will also increase because more energy is being delivered to the output.
