The invention discloses a circuit structure of a grain moisture content measurement device. The circuit structure comprises a device body which comprises a high frequency filter loop, an integrated sampling module, a DSP control module, a compensating current generation circuit module and a human-computer interaction module. The device body is accessed to a power grid through a parallel access point arranged between the power grid and the load so that the space occupation is low; the IGBT switching frequency can be enhanced, the output current ripple can be reduced, and thus the output LCL inductance is reduced, the device voltage withstanding requirement is low and the device of higher voltage level can be realized; the closed-loop control mode is used, the special program is invented, the real-time requirement can be achieved by using the least DSP processors, precise control of the load harmonic and reactive compensation can be performed and the power grid quality can be improved; multi-parallel centralized monitoring can be conveniently realized, installation and maintenance are convenient and long-term and stable working of the equipment under the environment of high-capacityand complex condition can be guaranteed.
Description
technical field [0001] The invention relates to a reactive power treatment device, in particular to a circuit structure of a grain water content measuring device. Background technique [0002] The circuit of the grain moisture content measuring device includes a power filter device, and it is difficult for the power filter device on the market to output a large current; although the cabinet structure can output a large current, it takes up a lot of space and high cost, which is not conducive to mass production and Cost control, inconvenient to achieve multi-stage parallel operation. When outputting a large current, the topology adopted is a two-level structure, and a compact modular product adopting a three-level topology is difficult to meet the requirements of a high current output. [0003] The object of the present invention is to provide a circuit structure of a grain water content measuring device to solve the problems raised in the above-mentioned background technolo...
