Abstract
Currently，analog control is used for voltage regulation in the DC-DC converter. The control strategy is represented by PI，PD，and PID controllers. These control methods should achieve high performance output control during a linear load condition. However，when the load is constructed by nonlinear elements such as the choke coils and diodes，it is impossible to keep same performance because circuit conditions cannot be constant. Furthermore，a digital load with a high-speed and irregular change characteristic appeared in recent years.Therefore，we proposed a digital control system that is using a DSP as a control core in this paper. In the digital control system，we adopted the Neural Network(NN) method because it is possible to allow flexibly in various states of the load. In the proposed method，the DSP will learn the circuit condition in real time and realizes high performance output voltage control instead with analog control method
