Abstract: A computer-implemented method simulates a system having multiple interconnected components in a network that couples at least one client computer to a server computer. The method includes: receiving simulation data over the network from the server computer, wherein the simulation data represents one or more characteristics of information that would be present in a particular system having two or more interconnecting components during the operation of the particular system. At the client computer, the method includes generating a first simulation display based on the simulation data for operation of the particular system, and receiving user input at the client computer. Also disclosed are methods for changing component values in a system, compressing waveforms, locally displaying signals from a probe point in a system depiction, processes performed at a server, data structures for displaying user interface screen for providing such information, and a method for circuit creation and use feedback.

Abstract: A high voltage analog solid state switch is disclosed which includes a pair of MOS FET's 10 and 20 having commonly coupled sources 11 and 21 and commonly coupled gates 13 and 23. A photovoltaic generator 30 and an opto-coupler 40 are connected in parallel between the commonly coupled gates and sources. The input node is connected to the drain of one transistor 10 while an output node is connected to the drain of the other transistor 20. The switch is turned on by application of light 32 to generator 30 to thereby positively bias the gates 13 and 23 and cause transistors 10 and 20 to conduct. The switch is turned off by application of light 42 to coupler 40 to thereby short the commonly coupled sources 11 and 21 to the commonly coupled gates 13 and 23.
