VIC-5 phase-locked loop

With these chokes and this cell, where is the resonance — and can this PLL reach it, hold it, and build the rise inside each gate?

Loading a circuit fills the slots; change any of them afterwards and the result is your variation on it. All saved circuits.

The parts

The water capacitor the loop has to find the resonance of.

What is in the cell.

The choke on the positive side.

What the charging choke is wound on.

The choke on the return side.

What the blocking choke is wound on.

Between the VCO's driver and the chokes, if there is one. About this part.

The drive

kHz

Where the VCO sits with no correction — the middle of its range.

V

The peak voltage applied across the loop — after the transformer, if there is one.

Hertz per volt of control voltage.

Volts per radian of phase error.

kΩ

The lag-lead filter's series resistor.

kΩ

The resistor in series with the filter capacitor.

µF

The filter capacitor.

Hz

The slow gate switching the locked drive on and off.

%

How much of each gate period the drive is let through.

Separate, or on one core with fields aiding or opposing.

How much of one choke's flux threads the other.

From the parts

Every number handed to the simulation that you did not type, and where it came from. Each derivation that ran a calculation links to that calculation's page with these numbers in, so it can be checked alone.

Before it can run

  • Choose the charging choke.
  • Choose the blocking choke.
  • Choose the cell.
  • R Series resistance 100 Ω

    No resistance recorded on any part; 100 Ω assumed.

  • V Drive amplitude 60 V

    The drive amplitude of 12 V stepped up through Flyback Mode 1:5 Step-Up (100:500). The 1 A primary current given to the ratio calculation is for its current figures only; the voltage ratio does not depend on it.

    Transformer step-up to the cell

  • No water chosen, so the cell is taken as full of distilled water at 20 °C. Pick a water to change that.
