Abstract

To address the demands for a wide voltage range and high efficiency in unidirectional low power applications, a semi dual active half bridge (DAHB) converter with soft switching capability and a voltage match trapezoidal modulation (VM-TZM) control are proposed. This converter has the fewest number of active switches among existing dual active bridge converters. With the proposed control law, the converter always works under voltage match condition, effectively decoupling the control variables while achieving low root-mean-square current. Besides, the active switches can realize zero-voltage-switching (ZVS) on and the diode can obtain zero-current-switching (ZCS) off within full working range. These characteristics and benefits of the proposed converter and control law are validated through an experimental prototype.

带电压匹配梯形调制控制的软开关半双有源半桥转换器

为了满足单向低功耗应用对宽电压范围和高效率的要求，提出了一种具有软开关能力和电压匹配梯形调制（tm - tzm）控制的半双有源半桥（DAHB）变换器。该变换器是现有双有源桥式变换器中有源开关数量最少的变换器。该控制律使变换器始终工作在电压匹配条件下，在实现低均方根电流的同时有效解耦控制变量。主动开关在全工作范围内可实现零电压开关（ZVS）导通，二极管可实现零电流开关（ZCS）关断。通过实验样机验证了所提出的变换器和控制律的特点和优点。
