Simple power saver

This simple power saver circuit is used to save electricity in our homes to avoid spending too much electric use . You can using an Auto Soft Starter for external circuit as function to reduce electricity power.

How it works power saver? 

This circuit of works to filter the AC voltage , and reduce the magnitude of the cosine curve AC current that will be read on the instrument KWH meters. KWH meters will work if there is a load wire passing through a coil of wire sensors to measure the AC current is passed, if the current through a lot of electricity. C1 and C2 worked as a deduction from stamping voltage if the switch is connected, so that equipment or components which enter the voltage was not much shocking.

Simple power saver circuit

Part List simple power saver circuit:

C1,C2 = 100pF / 400V or higher
C3      = 10uF / 400V non polar capacitor
Fuse   = 0.5W
S1      = Switch on/off
Use best quality capacitors
Use the circuit on each item that requires AC power house to besaved using voltage field of electronics goods. Or if you take the trouble to make on each item , then use immediately near the KWH meter, to disconnect to tke their input and issued again on output, should use the box to close the circuit.


  1. The voltaged mentioned for abiove ckt. AC or DC. e.g 100 pf 400 VAC of 100 pf 400VDS like wise another 10uf 400VAC of 10uf 400VDC.

  2. The circuit working on 220V AC, and KWH is
    reduced, because the capacitor serves as a clutch to avoid possible conflict of high voltage
    Thank you. for your visiting Circuit Schematic Electronics

    1. yes u can use it,, it can effect more save electricity

  4. and what happens when i use AC capacitor with that value mentioned, 24uf 400v

    1. more soft start, if you use electricity in to a electronicdevicem and more saving.

  5. After completion do i have to just plug it in and free socket and leave in?

    1. if you leave in and plug it again it no affect in your electricity

  6. capacitor jenis mana yang sesuai...

  7. which type of AC capacitors must be used, either starter
    type or run type.

    1. Hello amit kumar,

      you can using radial electrolityc capacitor for this simple power saver circuit.

  8. Does it reduce watts comsuption?
