ABSTRACT
Power technology, especially CNC power technology is one engineering technology
with strong practice, it services for every field. Modern information technology revolution,
that brought with the development of computer and communications technology, provides a
broad development prospects, but also makes a higher demands in power supply technology.
At the present time CNC current source on the market exists some shortcomings, such as
output precision is not high, the power density is relatively low, capacity with a load is not
strong, bulky, expensive, complicated operations, instability working state and so on. So the
major develop direction of CNC power is specialized for these shortcomings, and to reform
them. Digital intelligent power modules is made against the lacking of traditional intelligent
power modules, digitize can reduce uncertainty and human participating quantity of links in
the production process, and resolve some engineering problems effectively, such as
reliability, intelligence, product consistency problem and so on, and greatly improve
production efficiency and maintainability of the product. Therefore, high-accuracy CNC DC
current source has a lot of space to develop. In this design,STM32 MCU will be used as the
main controller of the whole system, it can achieve the multi-function, wide
range ,adjustable, and many other functions, providing better conditions for achieving
constant current and completing the design of CNC current source. It integrates A/D
converter, D/A converter and PWM module in STM32 chip, thus reducing complexity of
the system, keep the system simple, reliable and low price.
