Problems solved by technology

[0004] The purpose of the present invention is to solve the current technical solution and save the conventional parallel inverter through the high-speed DSP chip combined with the SPWM design to detect the balanced control of the output voltage and current. It requires high-precision same-frequency sampling and a stable voltage follower. This is a problem of relatively high cost in terms of software and hardware. To provide a parallel inverter that does not require high-speed CPU operations and whose output frequency can automatically follow the grid adjustment

Abstract

The invention relates to parallel inverters. It solves the problem that conventional technology requires high-precision sampling at the same frequency and stable voltage follower. The technical solution is: including power distribution module, CPU distribution management module, self-synchronization output module, constant current and constant voltage drive module and power conversion module, The power distribution module is respectively connected to the input end of the CPU distribution management module, the input end of the self-synchronization output module and the input end of the constant current constant voltage drive module, and the output end of the CPU distribution management module is connected to the constant current constant voltage drive module. The control terminal of the constant current and constant voltage drive module is connected to the control terminal of the power conversion module, the output terminal of the power conversion module is connected to the input terminal of the self-synchronization output module, and the output terminal of the self-synchronization output module is a parallel inverter The output end of the inverter, the feedback end of the self-synchronization output module is connected with the feedback input end of the CPU allocation management module. The invention does not need high-speed CPU operation, and the output frequency can automatically follow the grid adjustment.

Description

technical field [0001] The invention relates to a power conversion device, in particular to a parallel inverter. Background technique [0002] The rapid development of electrification has higher and higher requirements for the capacity, performance and reliability of the power supply system, which also promotes the continuous deepening of the research on power electronics technology. The realization of large-capacity power supply by parallel connection of multiple machines is recognized as one of the important directions for the development of power conversion technology today. The capacity of a single inverter power supply module is very limited. Expanding the capacity by connecting multiple modules in parallel can not only make full use of the advantages of the new full-control power switching device, reduce the volume of the system, reduce noise, but also improve the dynamic response speed and Versatility of inverter power converters. Conventional parallel inverters use...
