摘　　要：由于超级电容的一些特点,可以应用它的一种改进的半桥电路结构来防止蓄电池的大电流放电。这种结构可以使其电源在工作一定时间内不出现大电流放电,同时又不影响负载工作,它是在负载处于短暂的重载时,可以将之前存储在超级电容的能量输出来减小直流电源的输出功率。但是这种电路要正常工作需要对直流电源上的电流进行检测,再来控制超级电容输出的功率,考虑到实际应用中电流的检测、判断到最后产生相应操作的过程中需要一定的时间,即存在滞后性。因此,可以对该超级电容的半桥结构进行预测控制以补偿控制电路反应的滞后性。For the features of the supercapacitor, a half-bridge circuit based on it can be applied to prevent the high current discharge of the battery. When a power is working, the structure can be used to prevent the power from discharging large current, on the other hand not affecting the state of load within a certain time. For the reason that while the load is shortly overload, the energy stored in the supercapacitor can be extracted to reduce the output energy of DC power. Before the supercapacitor is controlled to output energy, the circuit of the DC power should be detected. However, considering the practical application, it takes a certain amount of time to detect the current, make decision and do the last corresponding operation, which will lead to lag in control. Therefore, it need predictive control in the structure to compensate the lag.
