【LTspice】004 Voltage Source 参数配置

目录1.DCValue2.PULSE3.SINE4.EXP5.SFFM6.PWL7. bv-函数式电压源1.DCValueLTspice的Voltagesource是我们必须了解的一个器件,任何一个仿真都会用到。下面详细介绍这个器件的设置。首先,设置一个直流电压,如下,直接输入DCvalue即可,serialResistance代表内阻,我们一般不指定。当点击【Advanced】,我们可以设置更多高级功能。如下,每一个功能后面括号里是实现这个功能需要编辑的参数。2.PULSEVinitial:初始电压;Von:高电平电压;Tdelay:延时时间,指仿真开始的0时刻到出现第一个波形的延时;Tri
