With the development of human civilization, human society on oil, natural gas and other non-renewable energy consumption is growing, so a negative impact comes, new energy development and utilization of homeopathy was born. With the world’s new energy industry, the domestic hot pursuit of new energy industry. Countries to invest heavily in solar power generation, wind and solar technology, not only for energy saving has a positive meaning, while enhancing national research capacity for far-reaching significance. To better implement the national energy saving policy, provide sophisticated technical civil process, the paper30KW frequency inverter principle and improve the system to do research and analysis and summary.The inverter is designed mainly for hardware circuit design optimization, in order to DSPIC33FJ32MC204-2for the control of the core based on the MPLAB IDE matlab software simulation and hardware circuit simulation, and demonstrate its feasibility in theory, be a hardware circuit build and experiment. Main contents and completed the following tasks:SPWM based on the theory first in a strong electric circuit design completed, including the following modules:three-phase full-controlled bridge rectifier circuit, the DC transformer circuit, three-phase PWM inverter circuit, smoothing filter circuit, high power external auxiliary circuits, protection circuit, wind and lightning protection grid inverter circuit, and related modules and the principle of detailed functional analysis and design optimization; to MATLAB as a simulation platform, the SPWM modulation algorithms for the simulation before the experiment, the modulation wave, the carrier waveform software simulation, design simulation by repeatedly confirmed its feasibility.Second, to build the inverter main circuit hardware test platform, in order to reduce research funding, to reduce test cost, the early use of23N60in the experimental tube instead of expensive power IGBT as switching devices for low-voltage low-power circuit open experiment, a detailed record of the experiment and waveform data, waveform data analysis, so that the control system programming support; hardware circuit of the module after repeated low-power (1KW) the successful completion of commissioning independent work under low-power, the compatibility of various sub-circuits integrated debugging and use the UC3846as the core of the hardware circuit as a low-power control system compatibility test under the system in1kw, small current environment, able to coordinate work, and stable performance. Experimentally confirmed the stability of the main circuit optimization program, the access control system R&D phase. Control system to DSPIC33FJ32MC204-2as a main control chip, complete the relevant external support circuitry, and drive circuit design, the final completion of the PCB production. Electronic control board for the welding debugging improvements, power-on test program simulation, electronic control panels by the MPLAB IDE simulation experiments to determine the improvement of non-isolated driver for the isolated driver circuit to reduce the complex electromagnetic environment of the micro-electromagnetic interference signals.Finally, the electronic control board and inverter main circuit through repeated testing, can stability test is completed, the electronic control board and power on the main circuit of the fine-tuning the experiment proved successful output stable electricity system. More design-oriented focus, designed to increase the aesthetic appearance, the use of CATIA3D graphics software, according to the circuit structure of the chassis sheet metal forming, thermal windows and other parts of the design, and complete the assembly design. Due to time constraints, the installed capacity has not been tested, but will work in order to complete the order in latter time.
