The switch in turn switches current flow through an inductor. The driver circuit includes a "Drive Node Voltage Dependent Impedance Circuit" (DNVDIC) that couples the gate to a supply voltage node. In one embodiment, there are two resistive current paths through the DNVDIC. A non-linear ...
u C (0 + )=u C (0 - ) i L (0 + )=i L (0 - ) Note : Only the voltage on a capacitor and the current through an inductor cannot chang abruptly 。 13 3. 电路中其他初始电压、电流的一般求解方法: 具体求法是: 画出 t=0 + 电路:在该电路中若 u C (0 + )= u C (0 -...
Setting the initial current through an inductor This approach is not recommended but an alternative to using the '.ic' statement to set the initial current through an inductor is to appendic=<current value>to the inductor value and uic to the .tran statement: Setting initial circuit conditi...
The stability of an interface between a liquid metal and an insulating atmosphere, in which an inductor generates a uniform alternating magnetic field, is investigated, with particular attention given to the influence of the electrical c... Garnier,Marcel,Moreau,... - 《Journal of Fluid Mechanics...
When the switch does actually open, the current flowing in the inductor will decay through the freewheeling diode. In order to study the effect of the inductor size on the decay time of the current, the simulation may need to be rerun many times. Since the time to reach steady state ...
The series RLC circuit consists of a resistor R, an inductor L, and a capacitor C connected in series. If the electric charge on the capacitor in the system is denoted as q(t), and the driving voltage is e(t), then the differential equation that describes the time dependence of the ...
A clock generation circuit 53 for microprocessor 52 comprises inductor 54, crystal 56, and capacitors 58, 60, and 62. The dock signal from the clock generation circuit 53 is used as the internal clock of microprocessor 52. The dock signal from the clock generation circuit 53 is internally div...

Another technique to minimize ripple is to use a hysteretic comparator to compare the output voltage to a reference voltage. The hysteretic comparator output drives a switching transistor that controls current in the inductor. However, it is difficult to generate accurate hysteresis as well as provide...
