,Unified Boundary Trapezoidal Modulation Control for Dual Active Bridge DC–DC Converter,e DC–DC converter is proposed in this chapter. The fixed duty cycle compensation and magnetizing current design are firstly introduced to achieve the zero-voltage switching (ZVS) of the power switches, which cannot be ensured with the conventional TZM control. As a result, all the power switches of
