Generator voltage regulator is an indispensable part of maintaining the normal operation of diesel generator set, which plays an important role in the safe and stable operation of the generator set. At present, there are mainly two types of regulator named transistor-based analog voltage regulator and microprocessor-based digital voltage regulator. In view of the advantages that the digital voltage regulator has incomparable with the traditional analog voltage regulator, this paper designs a digital voltage regulator based on the TMS320F28335 chip for a certain type of vehicle diesel generator. The input and output interface circuit of the digital voltage regulator is designed, including the analog conditioning circuit, the digital conditioning circuit, the excitation main circuit and the excitation driving circuit, etc., to fabricate the power board. The software minimum control system is designed by using the DSP minimum system with TMS320F28335 as the core controller, and the voltage and excitation current double loop adjustment mode is adopted. Set up a system experiment platform to test the regulator to meet the expected functional requirements.
