- The interleaving two - transistor forward converter succeeds to the advantages of the two - transistor forward converter , it has two units working alternately , the power loss of the converter is distributed and the output voltage ripple frequency is twice of the switching frequency
交错并联结构式的双管正激变换器,继承了双管正激变换器的优点,两个并联单元互补工作,分担了功率损耗,等效占空比扩大了一倍,输出电压的脉动频率变为功率管开关频率的两倍。 - The influence of various waterpower and configuration parameters on heat transfer is analysed and the rules of convective heat transfer coefficient and the ratio of heat transfer enhancement with mass flux are obtained . at the same time , we gain important results as below : as for resonance chamber with certain configuration , self - oscillation can be generated under suitable configuration and waterpower parameters . for the same configuration resonance chamber , the intensity of the self - oscillation is changed by the waterpower parameters
当流量及压差降低至一定程度时，共振腔还可能削弱换热；加热功率的提高会增加流体（水）的温度，流体的粘度会随着降低，这会减少对流体脉动的阻碍，使脉动衰减得更慢，而脉动幅度的增加会增强换热，故加热功率对有脉动的对流换热是有影响的；自振腔产生的流体脉动频率是自振腔固有频率或其整数倍,流体脉动频率过高或过低都不利于对流换热，存在一有利于强化换热的频率范围。 - Because of the clamping capacitor and the interleaved structure , it has some good features compared with other flyback converters , such as : the topology is simple and can be realized easily ; the voltage spike of the power switch is availably restrained and without leakage - inductance energy loss ; the ripple of the input and output current is reduced , correspondingly , the volume and weight of the output and input filter is also significantly reduced
由于箝位电容的加入,相对于其他类型的反激式变换器电路,该拓扑具有一些独特的优点:电路结构简单且易于实现;无需另加辅助开关管,实现了开关管的有源箝位,抑制了开关管的电压尖峰;提高了输入、输出电流的脉动频率,减小了输入及输出滤波器体积。 - ( 4 ) the influence of pulsation frequency on the drying process two special cases , in which the selected pulsation frequencies were 0 h / , and 83 h / respectively , were simulated and their simulation results indicated that the pulsating frequency of gas stream could improve the intensities of the heat and mass transfer during a pulse combustion spray drying process
