Abstract
According to the working principle of the BUCK DC/ DC converter, a digital control strategy easy to implement, based on the inductor current, is derived in this paper. Combined with the PID control method with hysteresis,a DC/DC control strategy with feed-back current is designed. The simulation and implementation are completed by using an example of Buck DC/DC, and the simulation and experimental results show that the proposed control strategy enables the Buck converter with good input voltage adjustment and switch error correction capability which meet the digital control application requires a high dynamic performance. And compared with normal conventional control method, it has the advantages easy to implement, simple algorithm, fast response, small overshoot, etc.关键词
