Finished ZVS Tesla coil power boost high voltage generator drive plate induction heating module production
This is the design of a foreigner flyback driver circuit, used to drive high voltage package, because of the zero voltage switching (Voltage Switching Zero) and the majority of fans are referred to as “ ZVS”. Because of its high power, low heat, simple and reliable by fans are widely used in driving the spark gap Tesla coil (SGTC) and Jacob, Marx generator, ladder.
The ZVS driver circuit are used in high-quality components, high reliability and strong. Input 12-24V/10A DC power. Output high voltage DC, the voltage is about 800 times the input voltage.
Product size: 74mm * 77mm
Input voltage: DC 12V-30V
Power requirements: less than 5A; 15V &ge 12V≥ 15A
Operating frequency: 30kHz-50kHz adaptive
Secondary parameter: 5T+5T
Input voltage and current output voltage maximum power
12V/5A about 60W 10000V
24V/10A about 200W 20000V
This driving the circuit components are original, never cut corners. &hellip circuit board for the double-sided board, the use of the entire back as a resonant loop of the line, the resistance is small, less heat, good heat dissipation, performance is not a single panel can be compared.
1 Military FR4-A material 1.6mm double plate circuit board is made, the power line is extra tin, and optimize the line width of the MOS tube drive line, the current carrying capacity is stronger!
All symmetrical wiring, low density component layout, the original heat dissipation is better! In particular, the capacitor (other people's board design mini, in particular, the 2 capacitors placed side by side heat dissipation)!
2 the use of 2 original disassemble IRFP250N for power FET, large current, small resistance, strong power, pay attention to the new Taobao 99% IRFP250N for domestic, actually inside small chip pin, a thin sheet of metal, the weight ratio of the original light a lot, the performance is not good!
3 professional factory custom large inductance (1.25 copper wire around the system), the work neatly, the performance is more stable, long time 15A current no temperature.
4 use the five rings 1% precision metal film resistance, smaller error, higher accuracy, temperature drift, good heat dissipation! Use more stable!
5 the use of extra large 25*24*16mm thickening type anti-static high quality heat sink, the heat dissipation effect is better, stability and life is greatly improved!
6 special custom two MKP brand 0.33UF 1200V BM in parallel to make the high frequency resonant capacitance, the capacity is enough.
PCB board, FR4-A board, the price of 8 yuan 1, size 75*77 mm
Kit of parts, assemble their own (where irfp250 is to disassemble parts, other new)

Driving high pressure package, output high voltage
For induction heating, pay attention to the driver board to add cooling fan. Commodity without heating coil, please make
About high pressure packGeneral black and white color TV sets of high pressure can be used regardless of models. The greater the power, the better. ZVS driver with the high pressure package is already high pressure overload work, so the breakdown of the damage is a normal phenomenon, not a high pressure package quality problems, please try not to long term work! (high pressure package is easy to use, please select high quality high power high voltage package).
High voltage package primary winding: primary winding, please use the 1.5MM square wire 5 circle +5 circle (that is, 10 circle center tap), the same direction around the system (wire, please bring your own or to the hardware store to buy home improvement wire) as follows
About discharge arc length: when the input voltage 12v/5A, high voltage discharge arc distance of about 1-2 cm. The greater the input voltage and current, the greater the output power, the discharge arc longer distance, the maximum input 30v/10A, the maximum length of up to 5 cm. If the arc is too short, please check if the input power is sufficient.
About powerOutput power depends on your input power, if you only 30W power supply, even if you do a 200W ZVS what, the output is not up to the 100W and 200W, so the input power must be sufficient power = voltage * current!
Matters needing attention
1 after the completion of the installation of a careful comparison of the drawings and check a few times, to confirm all the components of welding
2 please note that the driver board input terminal power positive and negative signs, check and confirm the power, to prevent the fire board
3 test machine voltage is recommended for small power 12V, to prevent the problem or to the wrong line led to burn board
4 driving plate limit input for the DC 30V, current 10A, do not recommend the use of the limit value, do not in the case of over-voltage over current operation. The driving plate is not suitable for induction heating, if used for induction heating, it is recommended that the input voltage is below 15V. For a long time or high power induction heating and cooling fan must be used, it will cause poor heat dissipation, MOS tube temperature is too high, will accelerate the aging and even burn MOS tube etc..
Note: high pressure hazard!!!
For high voltage output driven high pressure package, the use of Caution!, can not drink to play, not to the whole person!
