# Function Rectify2

Calculates voltages and currents behind a full-wave rectifier

## Description

The function $$Rectify1$$ calculates different voltages and the current behind a Full-wave rectifier with a charging capacitor and a load resistor.

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

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.

The drop-out voltage at the diode is taken into account. For silicon bridge rectifiers, a value of 1.4 volts for every 2 diodes is common.

With full-wave rectification with center tap and two single diodes, 0.7 volts is common.

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