Project Description: 500W Regulated Bipolar Power Supply for Amplifiers

This project is a regulated bipolar power supply (+VCC / –VEE) capable of delivering up to 500 watts, designed for high-quality audio amplifiers and other applications requiring stable dual-rail power. The design focuses on reliability, scalability, and efficient cooling.

Key Features:

• Output voltage: ±1.2V to ±37V (adjustable)

• Maximum power: 500W

• Supply type: Linear, regulated

• Bipolar output: Suitable for class AB amplifiers, preamps, and analog circuits

Core Components:

• LM317 – positive voltage regulator

• LM337 – negative voltage regulator

• BD139 / BD140 – driver/current booster transistors

• TIPC35 / TIPC36
