Conceptual Design Edit

Functional Description Edit

The power supply serves the task of converting the mains alternating current to direct current at suitable voltages for various parts of the amplifier.

Block Diagram and Description Edit

The power supply can be broken down into three main parts;

transformation: converting the 240VAC mains to a lower voltage usually via a transformer.

rectification: converting the AC signal DC, in the current design this is implemented by a full wave bridge rectifier.

filtration / regulation: smoothing the output voltage to achieve a signal that is as close as possible to flat DC, currently implemented using a capacitor.

Design Parameters Edit

More design parameters will be added further into the design process.

Input Parameters Edit

Voltage 240VAC

Output Parameters Edit

Voltage 30VDC
Current 1 A

Design Implementation Edit

The details of on-going design should be maintained here.

Circuit Diagram and Description Edit

The basic principle behind the power supply is to use four diodes arranged as a full-wave bridge rectifier to rectify the AC-mains, and the use a capacitor in parallel with the output to provide smoothing of the output signal.

Further circuitry will most likely be necessary clean the supply further.
