一种具有最大升压能力和最小开关频率的Z源逆变器改进PWM策略

Z-source inverter provides a competitive single-stage dc-ac power conversion with the capability of both buck and boost voltage regulation. In order to maximize voltage gain and to increase efficiency, this paper proposes an improved pulse-width modulation (PWM) strategy. By adjusting the shoot-through duty ratio of one-phase leg, it regulates the average value of intermediate dc-link voltage, whi...
