Splet15. apr. 2024 · 3. Output Voltage. Switch-mode power supplies usually have variable output voltages. But whatever the case is (fixed or variable), always ensure the power supply is rated for the needs of your application. A lower, higher, or unstable voltage could damage whatever device or circuit that is connected to the power supply. 4. SpletSwitching Power Supplies and RF noise Why are Switched Mode Power Supplies (SMPS) associated with radio interference? What are the typical sources of radio interference in a SMPS? How is a SMPS affected by received radio interference? How can the problem be solved? What is the source of the "buzzing" sound heard at the receiver?
