Abstract
A wide output range multi-channel constant current source is designed for the research of active structural vibration control using shape memory alloy wires. The corresponding design circuit can discharge large constant current for low voltage load and realize the precise discharging control. With digital control, the multi-channel constant current could switch each channel according to the control method with intelligent management employed. By testing, the range of current is 0~8A, within 1% control precision, while the range of operating temperature can reach -40°C~+125°C. Experiment results show that, with over-current and over-temperature protection, the designed constant current source could drive the SMA wires for smart structures, and the effects is good. The designed current source is also fit for other research that multi-channel large current supply is needed.
