Voltage Controlled Switch in LTspice The switch has three distinct modes of voltage control, depending on the value of the hysteresis voltage, Vh. If Vh is zero, the switch is always completely on or off depending upon whether the input voltage is above the threshold. If Vh is positive, th...
Failing to find a model for a momentary-contact pushbutton switch, I tried to see if I could use LTspice's voltage-controlled switch. (See attached .asc file.) I failed. Problems: 1. The VCS seems to be undefined when plopped down in my circuit. When I try to run the simulation ...
The article provides information on the use of switch-mode control supply. This power supply is ideal for the circuitry that drives high-side p-channel MOSFET switches often found in motor controllers. It's especially useful for designs where the motor's positive supply voltage exceeds the ...
In this circuit, a lamp is connected across the terminals of an inductor. A switch is used to control the current in the circuit, and power is supplied by a 6 V battery. When the switch is closed, the inductor will briefly oppose the change in current from zero to some magnitude but ...
The problem is when i have to modify the Control Voltage in order to light my lamp in a fade-in effect. This is where i got stuck and i really don't know what to do. I'm simulating your circuit with LTSpice and Multisim and the results are different (especially when modifying the ...
The LT4256-1/LT4256-2 are high voltage Hot Swap™ controllers that allow a board to be safely inserted and removed from a live backplane. An internal driver drives an external N-channel MOSFET switch to control supply voltages ranging from 10.8V to 80V. ...
The Class-E inverter has been selected, because it is a single switch inverter with a grounded MOSFET source terminal, and this leads to low costs and a simple control strategy. The presented design procedure ensures both zero voltage switching (ZVS) and zero derivative switching (ZDS) ...

the generated voltage can fall below or rise above the setpoint voltage before settling at the setpoint level. This behavior is dependent on the speed of the control loop. For an application in which the supply voltage must be tightly regulated, an accurate voltage during such load transients is...
