To create a square wave supply with a 100V amplitude, a duty cycle of 50%, and a frequency of 5-10Hz, you can use an electronic circuit known as an astable multivibrator using operational amplifiers (op-amps). Here's a basic circuit configuration that can generate the desired square wave:

Components required:

  • Two operational amplifiers (op-amps) such as the popular IC 741
  • Resistors (R1, R2, R3, R4)
  • Capacitors (C1, C2)
  • Power supply

Here are the steps to create the circuit:

  1. Connect the power supply (positive and negative terminals) to the Vcc and ground of the op-amps.
  2. Connect a resistor (R1) between the output of the first op-amp and the inverting input (-) of the second op-amp.
  3. Connect a resistor (R2) between the output of the second op-amp and the inverting input (-) of the first op-amp.
  4. Connect a resistor (R3) between the non-inverting input (+) of the first op-amp and the output of the second op-amp.
  5. Connect a resistor (R4) between the non-inverting input (+) of the second op-amp and the output of the first op-amp.
  6. Connect a capacitor (C1) between the output of the first op-amp and the ground.
  7. Connect a capacitor (C2) between the output of the second op-amp and the ground.
  8. Connect the output terminals of the circuit to your load or use an additional buffer stage if required.

Note: The values of resistors and capacitors will depend on the desired frequency range. You may need to experiment and adjust the values to achieve the desired frequency range of 5-10Hz and the 50% duty cycle.

Remember to exercise caution while working with high voltages. If you are not familiar with electronics or have limited experience, it is recommended to consult an expert or use pre-built equipment designed for generating square waves.
