Abstract

A universal variable current control platform based on DSP plus FPGA (digital signal processor plus filed programmable gate array) belongs to the technical field of frequency converting control. A modular bus structure is utilized. The variable current control platform comprises a DSP plus FPGA master control unit, a digital signal control unit, an analog signal control unit, a power supply unit, a protecting unit and a base plate bus unit. Signals among the units are transmitted through the base plate bus unit, namely all other units are connected with the base plate bus unit. The power supply unit powers the other units. The analog signal control unit transmits collected analog signals to the DSP plus FPGA master control unit through the base plate bus unit. The DSP plus FPGA master control unit then transmits digital signals to the digital signal control unit through the base plate bus unit. The protecting unit transmits fault signals to the DSP plus FPGA master control unit through the base plate bus unit. The universal variable current control platform has the advantages that development cycle is shortened favorably, extensibility is enhanced, and a modular universal hardware software platform is built.

Description

technical field [0001] The present invention belongs to the technical field of frequency conversion control, and proposes a general-purpose variant based on DSP+FPGA (DSP stands for Digital Signal Processing, Digital Signal Processing, referred to as DSP; FPGA stands for Field-Programmable Gate Array, Field-Programmable Gate Array, referred to as FPGA). The current control platform is suitable for the research of PWM rectifiers, dual PWM converters, multi-channel PWM controlled multi-level converters and high-performance closed-loop controlled power electronic converters. Background technique [0002] At present, converter control is widely used in AC frequency conversion speed regulation, power supply, power system transmission and distribution, and power quality control. In practical applications, the control objects and control algorithms are different. For example, in the wind power grid-connected control and the multi-level converter control in DC transmission, the requ...
