A FPGA based fast DC link voltage controller for stand-alone diesel engine driven generator systems

This paper presents a fast DC link voltage controller implemented with FPGA technology. The controller is designed for maintaining quality voltage supply in stand-alone diesel engine driven permanent magnet generator systems. Functional simulation and practical tests with a laboratory system were carried out and the results have shown that the controller is successful in quickly regulating the DC voltage level and keeping an almost constant voltage. The developed controller has the advantages of fast response, short developing period and low cost.
