(Unfortunately, the additional computation will cause the controls to become less responsive.)Īn input amplitude control is provided for convenience. While this improves matters considerably, one should increase the parameter in order to obtain more accurate ripple amplitude calculation for large inductance values. ![]() We attempt to remove the ringing using the Fourier transform. ![]() For large inductance values, transient low-frequency "ringing" causes difficulties in the computation of the ripple amplitude. This is done by sampling over the last several computed cycles. Ripple amplitude (rms) is computed and reported as a percentage of the mean output voltage. The rectifier provides half-wave rectification we can mimic full-wave rectification by using a full-wave rectified input voltage. The voltage-current characteristic of the rectifier (the function in the program) is typical of a solid-state diode however, the parameter allows the inclusion of significant internal resistance typical of a vacuum-tube rectifier. We have in mind the high-voltage, low-current application in vacuum-tube audio amplifiers. ![]() It seems there are combined LC pi filters available in a single monolithic. The plotted output voltage is computed by solving the system of three differential equations from applying Kirchhoff’s voltage law to each of the three loops of the circuit. You need to base the filter on the frequency you dont want.
