一种用于单相并网T型逆变器的梯形波控制新方法

Triangular conduction mode (TCM) is used in grid-tied inverters to achieve high efficiency by its soft switching feature. However, it suffers from a wide switching frequency variation over the whole power range, which impacts the weighted efficiency. To address this issue, this article proposes a novel trapezoidal wave control method for a single-phase grid-tied T-type inverter. By the proposed me...
