A DIY Induction Heater. This great little project demonstrates the principles of high frequency magnetic induction. The circuit is very simple to build and only uses a few common components.

In otherwords, the high voltage arcs from the Tesla Coil are modulated so that they create audio sound waves – the Tesla Coil becomes a plasma speaker. The Tesla Coil operates at 4MHz using a state-of-the-art Class-E switching topology that creates a virtually silent output arc that permits high quality audio reproduction. This Tesla Coil is one of our best demonstration pieces and its always fun to watch both children and adults jaws drop when they realize there are no speakers and that all the sound is eminating from the high voltage arc.

For even more fun and better low frequency response, use two together as a stereo pair. Available in both a standard and high power version. The high power version creates larger arcs and increased audio output with better low-end frequency response. RCA line-level connector – Connects to any audio source with line-level output – Strong electric field lights up fluorescent and neon lights with ease – Onboard controls allow user to adjust output power, modulation depth, and audio input levels – Step LED VU Meter and Status LEDs add extra dazzle!

Transformer size problem kVA? Are you talking about sizing the ‘dry-pack’ step down from the V 3 phase to the volt 1 phase? Or the overall service transformer?

Fri Jul 04 , Thu Feb 09 , I did not understand it myself until recently, but I now only see a great amount of misconceptions being spread over and over, which I would like to stop. It needs to be understood that any transformer or inductor can work only with AC, and will represent a dead short to any DC component.

Volt-seconds in positive halfwave need to always be same as volt-seconds in negative halfwave; although their shape is irrelevant. A flyback is just a transformer with relatively low magnetizing inductance due to large air gap introduced in it. It works by putting an amount of energy into this magnetizing inductance while switch is on and releasing it into secondary while it is off. If we drive the switch by constant duty cycle from NE , we have predetermined the volt-seconds we put into positive halfwave with each cycle.

The expected problem is, if we loaded the output of the transformer with an arc – there is absolutely nothing assuring that negative half-wave volt-seconds will be the same as what we predetermined. Due to low impedance of an arc the negative voltage is actually going to be clamped to some very low value. If we attempt to charge a large HV capacitor, like to run a tesla coil, the same will happen as capacitor basically represents a short to DC output.

In any case, when positive and negative Vs aren’t trimmed, the current will integrate up for their difference. This is how the DC component appears in the primary -not instantly, but over a period of several cycles. At some point the flux which follows the integrating current will saturate the core, decreasing the primary inductance heavily and overheating the switch.

Duty cycle span Schematic The schematic has been updated Nov 28, , to correct an error pointed out by this user: For further study and experiments the output control can be tied to ground to enable single end mode, the two output transistors will be in phase and can be paralleled for a higher output driving current. Its possible to implement features as soft start and over-voltage , -current protection with the dead time control on pin 4, I have chosen to wire this to ground which disables the DTC.

This is a versatile and experimental driver circuit and when at some point a final product is going to be made, it would make sense to build in these protective circuits. The outputs are each connected to the positive rail through a R 2W pull up resistor to bring the output signal up in amplitude. Duty cycle The TL have two error amplifiers which I for the sake of leaving no inputs floating have paralleled.

A flyback is not a toy! You must accept the fully consequences of your actions should you decide to build a flyback high-voltage circuit! This project involves high voltages several 10s of kV , which creates electric sparks that can easily jump an air gap. Despite the generally low current of a flyback circuit, the high frequency several 10s of kHz and whisper quiet operation can lead to complacency, especially because flyback arcs can appear to be harmless and due to their high frequency, may not feel like much while current is flowing!

Electrical arcs are also very hot and can set fire to most things.

The eddy current loss is a complex function of the square of supply frequency and inverse square of the material thickness. Magnetostriction related transformer hum Magnetic flux in a ferromagnetic material, such as the core, causes it to physically expand and contract slightly with each cycle of the magnetic field, an effect known as magnetostriction , the frictional energy of which produces an audible noise known as mains hum or transformer hum.

Stray losses Leakage inductance is by itself largely lossless, since energy supplied to its magnetic fields is returned to the supply with the next half-cycle. However, any leakage flux that intercepts nearby conductive materials such as the transformer’s support structure will give rise to eddy currents and be converted to heat. This energy incites vibration transmission in interconnected metalwork, thus amplifying audible transformer hum.

When windings surround the core, the transformer is core form; when windings are surrounded by the core, the transformer is shell form. At higher voltage and power ratings, shell form transformers tend to be more prevalent. Each lamination is insulated from its neighbors by a thin non-conducting layer of insulation. Thinner laminations reduce losses, [53] but are more laborious and expensive to construct.

Laminating the core greatly reduces eddy-current losses One common design of laminated core is made from interleaved stacks of E-shaped steel sheets capped with I-shaped pieces, leading to its name of ‘E-I transformer’.

They can be free running or triggered. There are various modes of operation: Linear – really a relaxation oscillator A capacitor driven with a current has a linear voltage ramp or an inductor driven with a constant voltage has a linear current ramp. Either of these can be used to generate ramps or relaxation oscillators. Active device saturation Here the ramp continues until the active device saturates Magnetic core saturation Here the ramp continues until the magnetic device saturates Voltage Breakdown Here a capicator ramps until there is voltage breakdown in a Neon tube or other voltage clamping device.

The post explains how to build a simple 12V solar charger circuit with boost converter capable of charging 12V battery from a 3V solar panel. For this reason the project is introduced as a hobby. We have employed an output circuit more streamlined compared to a conventional photovoltaic system design and driver transistor is “low voltage”. Circuit means knowledge of electronics and photovoltaic solar energy. Currently the bulk of electronic devices are created to work with a voltage of 12V.

With the higher increases of LED lights there isn’t any obstacle by somebody wanting to choose to live using a low voltage supply which enable it to take pleasure in electronic delights of living in the city. Circuit diagram 12V Solar Charger 12v solar charger circuit Circuit advantage versus Conventional Photovoltaic Solar Charger Set up The most important downside of solar energy is obviously precisely the same sunlight! The sun will never glimmer all day and night.

Our eyes adjust to variations in the level of the sun, but a solar panel reacts in a different way. When the sunlight offers solar radiation at reduced strength, ie, in the early hours of the morning and later mid-day, solar panel overall performance diminishes.
