Hi,
How can I create a 8Hz Sine Wave 220 volts signal. If
I convert the AC 220 volts to DC. Will I still get 220
volts? So what's the smallest circuit or device that
can make 8Hz sine wave out of the 220 volts DC. Thanks.
Dave

At how many amps?

Any amperage will do. I guess the steps I must take
is to put some diode to make the 220 volts 60 hz
becoming dc 220 volts. Then put some circuit to
make it produce 8Hz. Right?
What's the schematics of the circuit. As simple
as possible. Thanks.

You can use a phase shift oscillator to get the 8 Hz sinewave. Then
amplify it to your power level. At this frequency, a transformer
will
be quite large even for low power. It might be easier to use a
220VDC
power supply and a high voltage transistor.
What would be the input voltage to use with the Phase shift
oscillator. Let me know which is a better idea.
1. Use line power 220 volts AC
2. Use diode and turn it to 220 Volts DC (Direct Current)
3. Use phase shift oscillator to turn it to 8Hz 220 volts Sine Wave
or
1. Use 12 volts DC from car battery
2. Use phase shift oscillator to turn it in to 12 volts 8Hz Sine
Wave
3. Amplify the 12 volts AC to 220 volts AC 8 Hz (?)
Tnx.
Dave
