high voltage

I'm working on a project and I've run into a problem. I have a high voltage DC power source and I want to be able to turn that into pulsing dc or AC using a spark gap. Is there a way to control the on/off of a spark gap the same way you can control the on/off of a transistor/MOSFET?

Hello, I seldom have to work with high voltage/high power hardware, so I am looking for the safest low-cost approach. I am working with a TI Evalution Board/Reference Design for a Voltage Source Inverter. It requires a 350-400 VDC input (1.7A). My main objective or focus is on the firmware...

Hello and thanks in advance for any potential answers. Background: I am planning to use a DC to high voltage DC converter module (XP Power G40) for a electro-adhesion based project. It is a compact and isolated power supply module which takes 12V DC as maximum input and provides a proportional...

i made a hand made transformer and wanted to ask the forum how and with what should I power it. And will it even work.

Hi, I purchased a couple of the ubiquitous "electric arc lighter" devices off of Amazon because I was curious how the designers were able to pack a 3.7v to many kV step-up circuit in a package the size of a ballpoint pen. I tested out the device and indeed it is able to make a ~4 mm sustained...

Hey everyone! I am Nio. I am currently working on building a cable that is used at high power application (1.5kW). The connectors I used at the terminals are N type and HN type connectors so I had to use a RG401 cable. I bought one of Multicomp Pro make. The cable has internal conductor covered...

HELP!!! so, the thing is that i have been trying to build a resonant high frecuency circuit to control a variable capacitor, this capacitor can support high voltage and high frecuency but its variable due to the electrolite it contains.. so I have been tryin to desing it and have come with a...

Hi, I have been reading a lot about flyback driver circuits for generating high voltages. Tutorials on Youtube are a dime a dozen describing minimalist circuits to drive automotive ignition coils and similar. However these tutorials rarely describe the underlying design theory and considerations...

Hi, I have a high voltage electric livestock fence that runs from my house to a barn about 1/2 mile away. I want to build a communication device that makes use of this existing wired connection to transmit a low voltage signal (ideally ~12 volts) along the wire with ground return to complete the...

Hello all, I need to run a 12V/0.6A dc fan to cool the MOSFETs of an inverter with 1kV input. it would be overkill to use some power supply to step down the 1kV to 12V or any DCtoDC converter!.. I thought of using just a resistor divider to step down the voltage to an acceptable range to use a...

Hi, I want to build the DC2781A evaluation board by Analog Devices. Most of the passive parts I already have, so the building cost would be much cheaper for me. However, I wasn't able to find a distributor that sells the inductor of this schematic: RPT129NP-102MB by Sumida. Therefore, I'm...

Hi How can i get high voltage high frequency power supply. I have zvs drive with flyback transformer. The maximum what I'm getting is 50kv and 21kHz , im fine with voltage ,but the frequency not too much i need in mega hertz. Any help. Thanks

I am trying to calculate the energy delivered by a short electrical pulse. I am using an oscilloscope to capture the waveform and then exporting it to a CSV file. My scope took measurements at a rate of once every 8 microseconds which means that each time time value could potentially vary by...

Hi! I am building a device for a national competition ("Unge forskere") That should be able to sterilize hands with nothing but electricity. For this project, I need a High-Voltage power supply, capable of delivering 12(or so)kV at 30-100khz. Therefore my head automatically went to the very...

Hi, Usually most of the PCBs have solder masks but recently i have seen a PCB with only few tracks(high voltage/current) with solder mask open. when do I have to keep the solder mask open for traces?

Draw the dc output voltage and voltage across T3 in a Graetz Circuit when firing angle is 45 degree and u=30 degree.

Hello everyone, I'm trying to create a high voltage power supply with a flyback transformer, IRFZ44N and a 220 Ohm resistor. (200 ohm in the diagram should be 220 Ohm ) Here's my schematic. My problem is that the wires connected to drain and source of the mosfet becomes burning hot and melt the...

For reference, I have included the full schematic as an attachment and the board layout for reference. The general theory of operation: I have a Rasberry pi to act as a UI and the pi is connected to an Arduino via USB serial connector. The Ardunio sits on the board as a hat and this works...
