How does a magnetron work?
And the magnetic field is generated by using a permanent magnet. The excitation to the cathode of the magnetron is provided by a dc supply which causes the emergence of electrons from it. Here in this section, we will discuss the working of magnetron under two categories.
What is a high power magnetron?
High power Magnetrons and Magnetrons with variable output power utilise electronic control systems to supervise and adjust the high tension supply, anode current, output power and filament heating. These control systems should be checked on a regular basis, latest before the installation of a new Magnetron.
Why is a magnetron called a vacuum tube?
The reason behind calling it so is that the electric and magnetic field produced inside the tube are mutually perpendicular to each other thus the two crosses each other. A magnetron is basically a vacuum tube of high power having multiple cavities.
What power supply do I need to operate the magnetron?
In order to operate, the Magnetron requires 2 power supplies: The filament power supply serves to heat up the filament to a temperature high enough to emit a sufficient number of free electrons. This supply can provide an AC or DC voltage, with typical voltages ranging from 2.5 V to 15 V, and currents ranging from a few A to 100 A and above.
What is the working principle of magnetron?
The operating principle of a magnetron is such that when electrons interact with electric and magnetic field in the cavity then high power oscillations get generated. Magnetrons are majorly used in radar as being the only high power source of RF signal as a power oscillator despite a power amplifier. It was invented in the year 1921 by Albert Hull.
How does a magnetron switch work?
In a Magnetron system, the switching is accomplished by a Darlington transistor, which is actually a pair of transistors. When the first of these transistors detects a current from the trigger winding, it opens the second transistor to allow it to pass current to the primary coil.
Why does an electron move in a magnetron?
This is so because the moving electron does not experience the effect of the magnetic field and moves in a straight path. In case a small magnetic field exists inside the magnetron then the electron emerging from the cathode will slightly deviate from its straight path.
What is magnetron in microwave?
Microwave Engineering / By Roshni Y / Leave a Comment. Definition: A magnetron is a device that generates high power electromagnetic wave. It is basically considered as a self-excited microwave oscillator. And is also known as a crossed-field device.
