查询词典 converter

The boost converter is a voltage step-up and current step-down converter .the current source is synthesized from a DC voltage source by adding a large value inductor in series .in DC regulated power supply applications ,the voltage sink represents a large value capacitor in parallel with the load resistance .in the application of the DC motor control ,the voltage sink represents the back emf of the DC motor .the switching action produces a pulsating current .the capacitive filter smoothens the pulsating current and provides a DC voltage to the load

升压转换器是一个升压和降流的转换器。电流源是一个直流电压源添加一个大值电感串联合成的。在直流稳压电源的应用，电压降代表一个大值电容并联一个负载电阻。在直流电机的控制应用中，电压降代表反电动势的直流电机。转换行为产生一个脉动电流。一个滤波电容是这个脉动电流平和并且提供直流的电压负荷。
