Project Title: Digital Control PCB Development for 6 & 12 Pulse Rectifier Battery Charger
________________________________________
Scope of Work:
• Design of Control PCB to manage both 6-pulse and 12-pulse rectifier topologies.
• Embedded controller with advanced monitoring and charging control functions.
• Interface with rectifier thyristor gates (via driver circuits).
• Real-time control of charging profiles (float/boost/manual modes).
• High reliability and industrial-grade design for harsh environments.

Key Technical Requirements:
• Processor: DSP / ARM Cortex-M Series / STM32 or equivalent
• Inputs:
o 3-phase AC sensing (Voltage, Current)
o DC Output Voltage and Current sensing
o Temperature, Battery Voltage, and optional battery health signals
• Outputs:
o Gate pulse control for thyristors (synchronization with AC input)
o Alarms and status relays
o HMI / LCD interface
• Communication:
o RS485 – Modbus RTU
o TCP/IP – Modbus TCP
• Power Supply: 24VDC
• PCB Size & Mounting: Custom size
• Safety & EMC: Design to meet industrial standards (IEC/EN)
