Lesson 24 of 24 — High Frequency Plasma Learning Centre The High Frequency Plasma generator is not one component but a sequence of energy conversions. A regulated supply changes mains electricity into 12 V DC. A ZVS driver turns that DC into rapidly alternating current. A flyback transformer raises the voltage, capacitor sections accumulate energy, … Read more
High-frequency electrical systems rarely produce one perfectly steady frequency. Switching circuits create a fundamental rate and harmonics, while spark gaps generate short impulses followed by damped ringing across a broad spectrum. To understand a High Frequency Plasma generator, we must therefore measure more than one number. Lesson 23 of 24 — High Frequency Plasma Learning … Read more
How does a flyback transformer works? A flyback transformer can turn a low-voltage switching waveform into a much higher voltage. Although it resembles an ordinary transformer, it is designed to handle pulsed energy, rapid changes in magnetic flux and—in many applications—temporary energy storage within a gapped magnetic structure. Lesson 22 of 24 — High Frequency … Read more
How Does a Transformer Work? A transformer transfers electrical energy between circuits through a changing magnetic field. It can raise voltage, lower voltage, change available current, match impedance or provide electrical isolation—all without a direct conductive connection between its primary and secondary windings. Lesson 21 of 24 — High Frequency Plasma Learning Centre Transformers range … Read more
Lesson 20 of 24 — High Frequency Plasma Learning Centre Inductance is the electrical property that links changing current with magnetic flux and an induced voltage. Every current-carrying conductor has some inductance, but winding the conductor into a coil—and often adding a magnetic core—can make the effect much stronger. Lesson 20 of 24 — High … Read more
What Is Capacitance? Capacitance is the ability of a system to store separated electric charge—and therefore electrical energy—when a voltage exists between two conductors. The component designed to provide capacitance is called a capacitor. Capacitors appear in almost every kind of electronic equipment. They smooth power supplies, store short bursts of energy, block steady DC … Read more
What Is Electric Current? Electric current is the movement of electric charge. It is what carries charge through a wire, moves ions through a plasma, heats a resistor, energises a transformer winding and makes an electrical circuit do useful work. Lesson 18 of 24 — High Frequency Plasma Learning Centre The idea sounds simple, but … Read more
So, what is voltage? Voltage is the electric potential difference between two points. It tells us how much electric potential energy changes for each unit of charge moved between those points. Voltage is one of the most frequently used—and frequently misunderstood—ideas in electricity. It is often described as electrical “pressure,” which can be a useful … Read more
So, what is electromagnetic induction? Electromagnetic induction is the creation of an electromotive force—usually described as an induced voltage—when the magnetic flux through a conductor or circuit changes. It is one of the most important principles in electrical engineering. Generators, transformers, induction cookers, wireless chargers, guitar pickups, metal detectors and many high-voltage power supplies all … Read more
So, what is a magnetic field? A magnetic field is a region in which moving electric charges, electric currents and magnetic materials can experience a magnetic force. Magnetic fields surround permanent magnets, current-carrying wires, coils, transformers, electric motors, the Earth and even moving charged particles inside plasma. Magnetic fields are invisible, but their effects can … Read more
