Our enhancements to Spice have made simulating switching regulators extremely fast compared to normal Spice simulators, allowing the user to view waveforms for most switching regulators in Spending a few minutes, or hours, simulating the protection circuitry in LTspice helps to avoid expensive hardware respins due to EMC failures. When the voltage input to the voltage controlled switch is below the voltage threshold (LOW LEVEL), the switch becomes off Download LTspice 24. The OFF resistance can be 1GOhm if desired. poormystic. Explain how to use/make Hierarchical Blocks in LTSpice LTspice is a high-performance Spice III simulator, schematic capture and waveform viewer with enhancements and models for easing the simulation of switching regulators. I'm not sure what the coil inductance would typically be on a 24 volt contactor coil, I have The diode, of course, protects the transistor from back emf from the relay when the circuit is turned off.
