Calculates voltages and currents behind a half-wave rectifier

The \(Rectify1\) function calculates different voltages and the current behind a Half-wave rectifier with charging capacitor and load resistor.

The voltages in idle and under load, the ripple voltage and the current through the load resistor are calculated.

The drop-out voltage at the diode is taken into account. A value of 0.7 volts is usual for silicon rectifiers.

For the internal resistance of the power source, the resistance of the secondary winding of the transformer is essential. In the heavy current range, the resistance of the connection lines can also play a role. Transformerless circuits usually have a series resistor to limit the inrush current whose value (e.g. 5.6 Ohm) is used as the internal resistance.

As a result, the function returns an object in which the calculated values are contained.
