+# Fixed AC-DC Converter
+
+Simulation of the following circuit
+
+![circuit](ac2dc_01.png)
+
+To simulate the cirucit run the following command:
+```sh
+$ ngspice -b ./ac2dc_linear.sp
+```
+
+ensure you have gnuplot installed to generate the plot, it will create an image
+called `results/voltages.png`
