CONSTITUTION:The receiver 10 has the constant current circuit 11 flowing a given current I to the receiver input terminal. When the DC pulse of amplitude E1 is delivered, the receiving voltage E5 of the receiver 10 is E5=E1-Z1I. When the charge Q=CE5 (where: C is stray capacitance) is...
到目前为止,直观且精确的等效电路模型在数字脉冲宽度调制(Digital Pulse Width Modulated,DPWM)的经典DC-DC 变换器中罕有报道。本文以运行在电流连续模式(Continuous Current Mode,CCM)的数字控制同步DC-DC 变换器为对象,利用文献[28]提出的对传统离散迭代模型进行近似的建模思想,建立数字控制DC-DC 变换器的等效电路。
虽然模型预测控制已经广泛应用于电机控制器、并网逆变器等变流器的控制中,但由于DAB采用的移相调制方法与常规变流器采用的脉冲宽度调制(Pulse Width Module, PWM)方法有所不同,模型预测控制应用于DAB的相关研究尚不多见。 国内外已有的DAB模型预测控制大多基于SPS调制策略,没有应力优化特性。文献[27]提出了一种基于分组...
