A "chopper" (switching transistor) converts the DC voltage into a high-frequency pulse train.
Capable of either increasing or decreasing voltage. Switch-Mode Power Supplies
Output voltage is maintained through Pulse Width Modulation (PWM) , where the duty cycle (ratio of on-to-off time) is adjusted by a feedback mechanism to compensate for load or input variations. 3. Common Topologies A "chopper" (switching transistor) converts the DC voltage
The primary function of an SMPS is to transfer power from a source (AC or DC) to a load while regulating voltage and current. The process generally follows these steps: Switch-Mode Power Supplies
Different circuit configurations, or topologies, are used based on the desired output:
Typically power MOSFETs or BJTs that perform the rapid switching.
