Preamble

The programmable AC power supply is an important testing equipment which enable the testing of varies electrical devices. In the development stage of power converters, the debugging and testing of power converters will be more efficient with the programmable AC power supplies.

Objective

The objective is to design a programmable AC power supply using class D amplifiers.

Partial Specifications

The specification include:
1) Maximum power: 10kW @ peak load
2) Output voltage: 0-2200V (rms), three phase AC or three DC output
3) Frequency range: 0-1000Hz
4) Waveform: sine, square, or programmable
The programmable AC power supply is powered by 420VAC, 60Hz input.

Suggested Approach

The team should investigate:
1) the class D amplifier and operation principle. Class D amplifier is usually used for audio application with audio signal input. It can be employed as the programmable AC power supply.
2) the controller to control the output voltage to follow the input signal
3) the protection for the power supply.

Group Responsibilities

The group should response for designing the system via simulation model.

Student A Responsibilities

Student A response for the class D power circuit including the parameters of the passive components

Student B Responsibilities

Student B design the controller to follow the input signal.

Student C Responsibilities

Student C design the protection of the power supply at critical load.

Student D Responsibilities

Student D response for the overall simulation model.
