DSP-based digital control of inverter design
Abstract：After developing many years, analog controller is very nature, but it also has many disadvantages. With appearance and development of DSP, the digital control system has advantages of flexible control, high integration, strong anti-disturb ability, the realization of advanced control arithmetic and the convenience of real-time control. Digital control has been becoming one direction of modern power electronics development. The following is a study of this article: 1. PID control inverter digital control system to achieve (inverter digital control technology). Including the composition of the inverter and SPWM control technologies as well as the inverter model of the closed-loop system, as well as the emergence of the digital PWM mechanism.
2. DSP-based digital control of inverter hardware circuit design. TMS320LF2407A chips
which have done something, the inverter control system for the hardware to do the design, as well as digital signal processors for hardware circuit design to do.
3. DSP-based digital control of inverter design software. Mainly on digital PID control technology and system software design structure.
4. To control the inverter based on DSP Design and Implementation. TMS320LF2407A mainly used to construct a digital control system 1KVA.
