Electrical Equipment 12 PDH Discount Package

This online engineering PDH course provides a basic understanding of the physical concepts needed to understand the principles of semiconductors. To understand the principles of semiconductors, it is good to first understand the basics of atoms and energy levels within atoms.

Solid state is an electrical term that refers to electronic circuitry that is built entirely out of semiconductors. A semiconductor is a solid whose electrical conductivity is somewhat between good conductors and insulators. Semiconductors can be made of a single material or a combination of several different materials. In early semiconductor devices, germanium was often used. However in today's semiconductor industry, silicon is commonly used.

Most all electronics that we have today are built around semiconductors. These are special because we can very easily control how current passes through them. We don't have that option with metal conductors since metal conducts electricity under almost any condition. Because of this, semiconductors are ideal for the construction of microprocessors, computer chips or memory chips, which consists of millions of transistors packed onto a tiny piece of silicon.

This 4 PDH online course is applicable to students, professional engineers, service technicians, energy auditors, operational & maintenance personnel, facility engineers who are interested in gaining a better understanding in solid state semiconductors.

This online engineering PDH course provides technical guidance and design requirements for the operation and maintenance of auxiliary electric power systems.

Auxiliary power systems are used on engines or prime movers that convert hydraulic, chemical or thermal energy to mechanical energy with the output being either straight-line or rotary motion. Auxiliary power systems are commonly found in industrial plants or on large aircraft, naval ships and large land vehicles. They are also installed on some diesel locomotives, allowing the prime mover to be shut down during extended idle periods, while providing power and heat to maintain air pressure and to keep the batteries charged and the engine coolant water from freezing.

This 3 PDH online course is intended for electrical engineers, mechanical engineers, plant operators, construction managers and other technical personnel seeking an introduction to the operation and maintenance of auxiliary electric power generating plants.

This online engineering PDH course provides a basic understanding of Vacuum Tubes, explaining the basic theory, evolution and applications.

An electron tube is a device used for the processing of electrical signals. It consists of two or more electrodes inside a metal or glass tube which has been evacuated. Because a vacuum must be provided in the form of an evacuated enclosure in which the electrons can move without collisions with gas molecules, these devices are also called vacuum tubes or electron tubes in the US, and thermionic valves in Britain.

Although solid state semiconductors have replaced the electron tubes in most applications, there are still niche applications where electron tubes not only continue to see practical use, but perform their respective tasks better than any solid-state device. For example, tubes are still used in some high-power amplifiers, especially at microwave radio frequencies and in some hi-fi audio systems. There are a lot of items that still use electronic tubes such as medical equipment, communication equipment, test equipment, televisions, radios, welders, and many others.

This 5 PDH online course is applicable to students, professional engineers, service technicians, energy auditors, operational & maintenance personnel, facility engineers who are interested in gaining a better understanding of electron tubes.
