摘要
为拓宽DC-DC变换器的输入电压变化范围,二次型Boost变换器在新能源发电系统中得到了广泛关注,其数学建模对系统的设计与应用至关重要。鉴于此,通过引用脉冲波形积分法,建立了基于理想变压器的连续导电模式下二次型Boost变换器的功率级小信号模型,获得了输出电压、电感电流的数学表达式,导出了连续导电模式下峰值电流控制二次型Boos变换器的完整交流小信号模型。基于该模型,设计了控制环路,并通过了实验验证。
In order to broaden the input voltage variation range of DC-DC converters,quadratic Boost converters have received extensive attention in new energy generation systems,whose mathematical modeling is very important for system design and application.Therefore,the power level small-signal model based on ideal transformer was established with pulse waveform integration method for quadratic Boost converter worked in CCM(continuous conduction mode),mathematical expressions of output voltage and inductance current were obtained,and the complete AC small signal model of quadratic Boost converter worked in CCM with peak current control was derived.Based on this model,the control loop was designed and verified by experiments.
