  • How to Build a Switch Mode Power Supply Circuit with an

    In this project we will show how to build a switch mode power supply circuit with a MC34063 chip. A switch mode power supply is also called a switched mode power supply or a switching mode power supply. A switch mode power supply is a power supply that regulates a certain power output. A switch mode power supply switches on and off to keep the This circuit board contains 6 bandpass filters to reduce harmonic output. Each filter is relay switched by grounding the appropriate line. This board also includes RF output voltage and current sensing to detect SWR variations. As the output SWR diverges from 50 ohms it is evidenced by output voltage and / or current changes.
