Abstract :
Most current electronic equipment requires a DC current with a lower
voltage for operation. Therefore, almost every electronic equipment has a circuit
that functions to convert an electric current from an AC current (Alternating
Current) into a DC current (Direct Current) and also to provide a voltage
corresponding to the electronic circuit. The circuit that converts AC current into
DC is called a DC Power Supply or in Indonesian is called a DC power supply. In
this thesis how to make a Buck Converter circuit with the aim that each input
voltage and resistance are changed to the desired output voltage.
To make the output voltage remain in accordance with the desired value, a
lead compensator is added which functions as the output voltage controller. Lead
compensators in general will speed up system responses and increase system
stability.
he simulation results show that the lead compensator can make the output
voltage (output) stable or stable even though the input voltage (input) and load
are changed. And after the Buck Converter circuit is added the lead compensator
response graph the output voltage (output) becomes faster and more precise in
accordance with the desired output voltage
