High Voltage EHT Supply Controller Kit with Arduino Uno & OLED: Build a 10kV Supply Safely

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

This kit transforms a ZVS flyback driver and HVDC multiplier into an instrument-grade 10 kV supply. The Arduino Uno reads the output through a precision 1000:1 divider using an ADS1115 ADC, then dynamically adjusts PWM duty cycle to limit voltage exactly where you set it. An OLED display shows live readings, and the entire assembly sits inside a purpose-built safety enclosure. Whether you’re building a Tesla coil exciter, an electrophoresis rig, or a physics lab demonstrator, you get controllable, repeatable high voltage without the guesswork.

What You'll Build

A fully self-contained, microcontroller-managed EHT power supply. The Arduino enforces soft-start ramp-up, sets a maximum output ceiling, and continuously monitors the HV bus through five series-connected 100 MΩ resistors. Every reading displays on the 0.96-inch OLED: actual kV, duty cycle percentage, and system status. Because all parts arrive as one tested set, your time goes into understanding the control loop — not hunting down mismatched components.

What You'll Learn

• Designing and enforcing high-voltage safety protocols with a dedicated isolation enclosure
• Interfacing a 16-bit ADS1115 ADC with Arduino for high-impedance voltage measurement
• Programming a real-time closed-loop PWM controller that regulates a ZVS driver output
• Building an intuitive OLED user interface that displays live voltage and system status
