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、...

The Buck-Boost Converter block represents a DC-DC converter that can either step up or step down DC voltage from one side of the converter to the other as driven by an attached controller and gate-signal generator. Buck-boost converters are also known as step-up/step-down voltage regulators...
Buck-Boost Converter With Sample And Hold Circuit In Current Loop In an average-current mode control type buck-boost PWM converter, a sample and hold circuit is inserted in the current loop to avoid problems associated with ripple of the average inductor current demand signal. The rippling averag...

A comparative analysis of Boost and Buck-Boost Converter for power factor correction (PFC) with diode bridge rectifier is discussed in this paper. Boost and Buck-Boost PFC converter faces very high THD and poor PF in open loop control. Thus Hysteresis Band Current controller is used to reduce...
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...
The buck–boost converter is a type of DC-to-DC converter (also knownas achopper) that has an outputvoltagemagnitude that is either greater than or less than the input voltage magnitude. It is used to “step up” theDC voltage, similar to atransformerfor AC circuits. ...
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...
