摘要： PROBLEM TO BE SOLVED: To provide an inverter that prevents the overload of a diode due to a recovery effect and supplies power to a power source.SOLUTION: An inverter includes two intermediate circuit capacitors C1 and C2 and first to fourth semiconductor switches S1 to S4. A common connection point SWP between the second and third semiconductor switches S2 and S3 is coupled to a supply power source Uac via a choke L1. The inverter includes first and second diodes D1 and D2 that are connected in series and their common connection point has the center voltage level of 0 V, and a second connection point between the first and second diodes D1 and D2 is coupled to a common connection point between the first and second semiconductor switches S1 and S2 or a common connection point between the third and fourth semiconductor switches S3 and S4. Additional chokes L2 to L6 are coupled to the common connection points among the first to fourth semiconductor switches S1 to S4, and a path for passing a free-wheel current is formed by additional semiconductor switches S5 to S9.

摘要： PROBLEM TO BE SOLVED: To provide a method of operating an inverter enabling improved efficiency and an inverter for performing the method. SOLUTION: To convert direct current voltages +U_ZL and -U_ZL of a solar generator G to an alternating current voltage U_Netz to be supplied to a power supply N, an inverter includes a step-up circuit H, an intermediate circuit Z, and a step-down circuit T. The step-up circuit H boosts the direct current voltages +U_ZL and -U_ZL when the direct current voltages +U_ZL and -U_ZL are smaller than a peak-to-peak maximum value of the power supply voltage U_Netz. The step-down circuit T steps down intermediate circuit voltages +U_ZH and -U_ZH to the voltage U_Netz that is lower than the voltage actually required by the power supply N. The step-up circuit H dynamically boosts the direct current voltages +U_ZL and -U_ZL to a value actually required by the power supply N, and temporarily provides a voltage curve that is almost a sine wave in relation to the intermediate circuit voltages +U_ZH and -U_ZH.

解决方案：为了将太阳能发电机G的直流电压+ U_ZL和-U_ZL转换为供给电源N的交流电压U_Netz，逆变器包括升压电路H，中间电路Z，和降压电路T.当直流电压+ U_ZL和-U_ZL小于电源电压的峰 - 峰最大值时，升压电路H升压直流电压+ U_ZL和-U_ZL U_Netz。降压电路T将中间电路电压+ U_ZH和-U_ZH降低到低于电源N实际需要的电压的U_Netz。升压电路H动态地提高直流电压+ U_ZL和 - U_ZL为电源N实际需要的值，并暂时提供相对于中间电路电压+ U_ZH和-U_ZH几乎为正弦波的电压曲线。版权所有（C）2011，JPO＆INPIT
