【摘要】 双向可逆PWM控制补偿型稳压电源具有稳压精度高、效率高、体积小等优点。为了保证电源质量,主电路结构中电感、电容等参数的确定至关重要。通过对电路工作情况的分析,从滤波的角度出发,给出了主电路电感、电容等参数的详细计算公式,并举例计算。计算参数时,为减小体积,在满足要求时,滤波电感取小值,电容取大值;直流侧平波电容要按逆变时直流电压升高限幅来选取,为保持稳压精度,此电容尽可能取大值。更多还原

【Abstract】 Bidirectional reversible PWM control compensation regulated power supply has high precision,high efficiency,small size,and etc.In order to ensure that the power supply quality,the inductance,capacitance and other parameters of main circuit structure are very important.Through the analysis of the work of circuit,from the point of view of the filter,the main circuit inductance and capacitance parameters of the detailed calculation formula were given,and an example calculation was also listed.When calculate the parameters,to reduce the size and to meet the requirement,the filtering inductances should take the small value,and the capacitance should take the big value;DC side flat wave capacitance was chosen according to the inverter DC voltage amplitude limit when rise.To maintain the accuracy,the capacitance should take the big value as far as possible.更多还原
