LTspice, 50hz and linear power supply circuits.
This page contains 50hz and linear regulator power supply circuits for operation on LTspice.
As always simulation will not show all aspects of the performance of the real circuit. There will be circuit parasitics which are not included in these simulations.
The basic circuits here are .............
- A 50hz transformer followed by rectification, then filtering.
- A linear regulator showing all internal waveforms.
