What is Zvs induction heater?
The zvs induction heater board is made of high class magnetic glass tube and copper core, which has high temperature resistance. In the meantime, zvs induction heater is a device that heats up quickly and avoids overheating and protects the module.
How does a ZVS induction heater work?
The ZVS oscillator pushes and pulls current though a coil around the object that is being heated. This constant changing of the current’s direction creates a fluctuating magnetic field. This induces many small eddy currents in the metal(refer to the diagram above).
What should the input voltage be on a ZVS?
When you first power on your ZVS driver, start with 12v input to make sure everything thing is working. Then you can increase the input voltage up to 36v. You can power the ZVS driver above 36v, but then you risk blowing up your driver, check step 7 for instructions for modifying your ZVS driver to handle higher input voltages.
What could be alternative technique to control the power to the ZVS driver?
What could be an alternative technique to control the power to the ZVS driver? For repeat-ability I would suggest that you require some form of PID temperature control. You could use a simple thermostat but that would not present a repeatable temperature profile given atmospheric variances, etc.
How does a ZVS oscillator board work?
This provides the 40 volts 10 amps that powers the ZVS driver board. It first uses a streetlight transformer to step down the 110 volt mains current to 40 volts. This is then rectified and filtered to achieve a clean DC voltage that is fed to the ZVS oscillator board.
Why do I need an inductor for my ZVS driver?
In general, if you want a higher voltage, the inductor should have an higher value, if you want more current, the inductor should have an lower value. Also, an inductor is a ‘must’ for the ZVS driver, without it, your ZVS driver may work poorly or not work at all.
