3-Phase Voltage Supply Simulator

Click For Summary
SUMMARY

The discussion centers on the challenges faced by educational institutions in setting up a three-phase voltage supply for power electronics experiments, primarily due to safety concerns and high costs. A proposed solution is to simulate a three-phase voltage supply using a circuit that closely mimics the characteristics of an actual three-phase source, including adjustable voltage amplitude from 0V to 20V and indicators for phase failures. The design must ensure optimum load voltage regulation while maintaining safety standards. A multi-winding transformer is suggested as a viable method to generate three-phase power from a single-phase source.

PREREQUISITES
  • Understanding of three-phase voltage supply concepts

In the study of power electronics, many tertiary education institutions faced problem in
setting up an electrical lab where experiments are conducted using three-phase voltage
supply. The difficulty arise was mainly owing to student safety factor. Also, the costs for
such experiments are relatively high which further burden the institutions. However, the
understanding of such subject is best enhanced through hands-on experience. Thus,
conducting the course without any hands-on might not be efficient.

One solution to these problems is to simulate the three-phase voltage supply at lower
amplitude and conduct the experiments using low power rated loads. It is important that the
simulated voltage supply has close relationship with the actual three-phase source.

Theoretically design a three-phase voltage supply simulator circuit that will solve the
engineering problem define in the main section of the assignment.
The theoretical design should conform to the following product specifications:
• The simulated 3-phase voltage supply has the wave shape, frequency and phase
differences of an actual 3-phase voltage supply.
• 0V to 20V user adjustable voltage amplitude.
• There should be indicators to show the failure of respective phases in case there is any
short circuit occurs in any of the phases.
• Optimum load voltage regulation.

Forumers,
Can you help me in solving this problem? I do not know what is a 3-phase voltage supply and I do not know how the circuit looks like. Can anyone give me some guidance on where how to start off?

Thank you to all..

It's very clear. A multi winding transformer can create three phase from single phase. You control the source impedance on the single phase side so that dangerous current levels are impossible. Wind your own or buy one commercialy. A web search reveals many for sale.
