The ISO120 and ISO121 are precision isolation amplifiers incorporating a novel duty cycle modulationdemodulation technique. The signal is transmitted digitally across a 2pF differential capacitive barrier. With digital modulation the barrier

龙格库塔法电机启动过程的暂态分析，电机内角接时，只有c相接入电源-Runge-Kutta method the motor to start the process of transient analysis, motor angles then, only c relative to access the power

带直通的三相逆变器的SPWM程序。本程序对应于新型的逆变器拓扑结构，可以实现电路的短暂短路运行，而不损坏主电路。-With direct three-phase inverter SPWM procedures. This procedure corresponds to the new inverter topology transient short-circuit operation of the circuit, can be achieved without damage to the
