The main ideas of the thesis and the contributions to the resonant dc - link area are also listed in this chapter . a novel control strategy for the two - amplitude actively clamped resonant dc - link is proposed in chapter ii . it neglects the bus short circuit time adjuster and stabilizes the clamping voltage by a pi regulator so that the obtained link frequency is improved and the link losses are greatly reduced 第二章针对双幅控制技术在单相桥式电压源逆变器中的应用为范例进行研究，提出了直流母线无短路控制和通过pi调节环稳定箝位电压的双幅谐振控制策略，进一步提高了母线振荡频率，减少了直流环节损耗。
