The most common form of VSD technology in the air compressor industry is a variable-frequency drive, which converts the incoming DC and then back to a quasi-sinusoidal AC power using an inverter switching circuit.

With Michalski he wrote his first English articles, entitled " A System of Programs for the Synthesis of Switching Circuits Using the Method of Disjoint Stars " presented at the 1971 IFIP Congress in Ljubljana, Yugoslavia.

In a switching circuit, the idea is to simulate, as near as possible, the ideal switch having the properties of open circuit when off, short circuit when on, and an instantaneous transition between the two states.

The use of relays for the logical control of complex switching systems like telephone exchanges was studied by Claude Shannon, who formalized the application of Boolean algebra to relay circuit design in A Symbolic Analysis of Relay and Switching Circuits.
35.
The thesis, " A Symbolic Analysis of Relay and Switching Circuits, " was largely motivated by the telephone industry's need to find a mathematical language to describe the behavior of the increasingly complex switching circuits that were replacing human operators.

Precautions must usually be used when switching circuit breakers, such as standing off to the side while switching to keep the body out of the way, wearing protective clothing, or turning off equipment, circuits and panels downline prior to switching.
38.
With Claude Shannon, before and during his time at Bell Labs, he coauthored " Gedanken-experiments on sequential machines ", " Computability by Probabilistic Machines ", " Machine Aid for Switching Circuit Design ", and " Reliable Circuits Using Less Reliable Relays ".
39.
In what has been described as one of the most important master's theses ever written, he showed how Boolean logic, in which problems can be solved by manipulating just two symbols, 1 and 0, could be carried out automatically with electrical switching circuits.
40.
In the 1930s, while studying switching circuits, Claude Shannon observed that one could also apply the rules of Boole's algebra in this setting, and he introduced "'switching algebra "'as a way to analyze and design circuits by algebraic means in terms of logic gates.
