Converter Topology You can model this converter as an inverting buck-boost converter with a physical signal gate control port or with two electrical control ports, or as a four-switch buck-boost converter with an electrical control port. To select the converter topology, set the Modeling option ...
一、连续状态 (CCM) 根据伏秒特性(voltage-second characteristic) 可得电感两端的电压与时间之间的关系为: VdDTs=Vo(1−D)Ts 根据电感电流在开通和关断过程中变化率相同同样也可以得到相应关系: VdLDTs=VoL(1−D)Ts 因此, VoVd=D1−D(1) 另外, Io=ID=IL⋅(1−D)(2) IL=Io1−D(3) 二、...
A buck-boost DC-DC converter (Figure 1), also called a buck-boost regulator, is an electrical or electronic circuit that is one of the three most commonly used DC-DC switching regulator topologies. A buck-boost converter produces a DC output voltage that can be either bigger or smaller in...
Boost regulators are more difficult to design than buck regulators, regardless of whether we control the output voltage or the output current. The average inductor current in a continuous conduction mode (CCM) boost converter is equal to the load current (LED current) multiplied by 1/(1 - D)...
This paper proposes a novel tapped-inductor bi-directional buck/boost (TI-B-buck/boost) topology, which can overcome the drawback of non-isolated bi-directional DC-DC (BDC) that its transfer ratio is restricted in a small range. This paper analyzes the principle and characteristics of TI-B...

The cyclically switching circuit, a boost-buck converter in optimal topology, without load capacitor, is analysed by using the tool familiar to engineers, the Laplace transform. The key to this approach is the use of the equations of the recently defined circuit element, the aiternor. A ...
