TIDA-010086

Digital control cost-optimized 10-A battery formation and test reference design

TIDA-010086

Design files

Overview

This reference design provides a cost-effective solution for battery formation and test applications. This design uses the C2000™ real-time control MCU for high-resolution pulse-width modulation (PWM) generation, and constant-current (CC) and constant-voltage (CV)
control loops. It efficiently utilizes the MCU, and does not require a precision digital-to-analog converter, which saves more than 30% in the bill of materials. The flexibility of current and voltage loops in software allows users to achieve multiple current and voltage levels output with one design.

Features

Bidirectional current control up to 10 A with less than ±0.01% accuracy
C2000 on-chip 12-bit ADC achieves control accuracy better than ±0.05%
Parallel up to 8 channels for wide output current range
Flexible digital constant-current and constant-voltage control loops
Channel-to-channel crosstalk error below 0.01%
Multilevel protection in hardware and software for reliable power supply design
