The relativity of instructions of motor control digital signal processor (MCDSP) in the design is analyzed. A method for obtaining a minimum instruction set in place of the complete instruction set during generation of testing procedures is given in terms of the processor presentation matrix between micro-operators and instructions of MCDSP. 相似文献

The principkle of Single-to-single phase matrix electric power conversion is further studied and the conversioin swith function is introduced into conventional rectifier-inverter,thus a general character of the two conversion techniques is discovered.It is characteristic of the switch functiion to follow mains voltage distrotion and mains frequency drift,By utilizing the merit,unidrectional switch duty-rations of the inverter follow the variation of DC-link voltage automatically,thus the size of DC-link electrolytic capacitor can be redued considerably,bringing about improved mains side power factor.Corresponding topologies and theoretical and theotor can be reduced considerably,bringing about improved mains side power factor,Corresponding topologies and theortical and theoretical derivations are given,and so are the simulation results,based on which it is confirmed that the single-to-single phase matrix conversion technique is potentially useful in large scale production,and the introduction of switch function can yield good economic returns. 相似文献

Multilevel inverter has become increasingly popular in recent years due to advantages of high power quality waveforms ,low switching losses,and high-voltage capability. A novel multilevel inverter with minimum number of separated DC sources is presented in this paper.Three-phase output voltages of this inverter can easily be balanced they are synthesized by using the same DC sources.A harmonic reduction method eliminating both the 5th and 7th harmonics is proposed.Finally,comparison results and spectral analysis are presented. 相似文献

A realization of three phase to three phase matrix electric power converter(33MC) with practicality is depicted,which is characteristic of modular configuration,simple and safe and semi-natural semi-forced two-step commutation strategy,general over-current protection circuit,flexible generalized switching functions,combined bilateral power swotches,and so on.A new approach to manufacturing-oriented 33MC comes forth,which is composed of 3 modular three phase to sigle phase non-square matrix electric power converters(31MC). 相似文献
