Switch Mode Power Supply (SMPS)
Switch Mode Power Supplies(SMPS) are an extraordinary array of high frequency alternative. These are the Switching Regulators offers higher efficiency then linear regulators. In addition, SMPS can step-up, down and invert the input voltage.
Advantages of Switch Mode Power Supply
- Change the output voltage level(step-up or step-down).
- Isolate the output from the input.
- Provide the user with a means to vary the output
- Can get constant output at variable input.
- Stabilize the output against the influence of :
- Source changes (source effect)
- Load changes (load effect)
- Temperature changes ( temp. Effect)
- The passage of time ( time effect or drift)
- Output short circuit protected.
Applications of Switch Mode Power Supply
- Machine tool industries
- Security systems (Close Circuit Cameras)
- Where very less size and weight is required
- Audio and Video application
- Support supplies with PLC ? s
