Principle of Energy Storage Switch | Nader Circuit Breaker

The so-called energy storage means that when the circuit breaker is de-energized (that is, when it is opened), it opens quickly due to the spring force of the energy storage switch. Of course, the faster the circuit breaker is opened, the better. This is to have enough power to separate the contacts when the segmentation fault has a large current (excessive current will melt the

A linear power supply (non-SMPS) uses a linear regulator to provide the desired output voltage by dissipating power in ohmic losses (e.g., in a resistor or in the collector–emitter region of a pass transistor in its active mode). A linear regulator regulates either output voltage or current by dissipating the electric power in the form of heat, and hence its maximum power efficiency is voltage-

Power Supply Circuit Explained

What is a power supply circuit? A power supply basically takes the power input from a power source and converts it into a suitable current and voltage for the electrical load; hence the name "power supply," which means supplying power to the load.However, it also has other additional benefits, such as being able to cut power in case of a short circuit, filtering out
