ATX power supply design + simulation

Modern desktop computers require a high power rated supply that can provide multiple voltage rails.

As part of the Power Electronics course, I designed the principle subsystems for an ATX power supply, with +-12V, +-5V and 3.3V rails.

A hardware version was not produced, but extensive simulations were done in LTSpice.

Knowledge gained:

• Power factor correction
• Flyback converter design
• Voltage standby systems
• Conducted emissions
