Construction of FPGA Based Hardware Controller for Autonomous Decentralized Control for UPS Application

Design concept of FPGA based hardware controller is proposed with basic modules for the development of power electronics applications. Also an autonomous decentralized control system for single phase UPS inverter with FPGA based hardware controller using software CPU core is described. Progress of FPGA technology makes it possible to include the software macro CPU core into the FPGA chip, a high flexibility can be realized for the construction of the control processor in power electronics application. But the basic modules for power electronics application are not enough in the environment of FPGA development platform. In this paper, several modules are presented for power electronics applications, and also proposed an autonomous distributed control system for single phase UPS inverter with FPGA based hardware controller using CPU core. The advantages of FPGA based hardware control system are discussed.
