Electromagnetic Interference Source Test System for Marine Power Electronic Rectifier.

In order to improve that testing performance of the electromagnetic interference source of the ship power electronic rectification device, the electromagnetic interference source test system of the ship power electronic rectification device is designed, the design method of electromagnetic interference source test system for ship power electronic rectifier based on discrete distributed ADSP-BF537 logic control and pattern recognition is presented. The invention relates to a local bus control method for an electromagnetic interference source test system of a ship electric power electronic rectification device, which is composed of a ship power electronic rectification module, a bus control module, a modulation and demodulation module, an upper computer information transmission module and an automatic identification module, the invention adopts the ISA/EISA/Micro Channel expansion bus to carry out the command loading of the electromagnetic interference source test of the ship electric power electronic rectifying device, and combines the discrete distributed control method to carry out the high-precision identification and the program compilation of the electromagnetic interference source test of the ship power electronic rectification device, and adopts the logic ADSP-BF537 as the core processor, the instruction read-write and the compiling operation of the electromagnetic interference source test system of the ship power electronic rectification device are carried out. In that ARM embed microprocessor environment, the hardware module design and the bus development of the electromagnetic interference source test system of the ship power electronic rectification device are carry out, an internal clock oscillator is designed, and the protection performance of the electromagnetic interference source test system of the ship power electronic rectification device is improved. The results of the system test show that the reliability of the electromagnetic interference source test is good, the precision of the automatic control is high, and the self-adaptive judgment of the electromagnetic interference source test of the ship power electronic rectifier is improved.
