High Voltage Multiplier (10x – 100kV DC)

Achieve unprecedented high-voltage DC outputs with our versatile High Voltage Multiplier, designed with both reliability and efficiency as its main focus. Now available in either positive or negative polarity configurations, this module is based on the renowned Cockcroft-Walton voltage multiplier design. It delivers exceptional performance and is ideal for demanding high-voltage applications such as scientific experiments and plasma generation. Encapsulated in solid epoxy for superior insulation, it sets the standard for reliability in high-voltage systems.

Key Features:

• 10x Voltage Multiplication: Convert up to 10kV AC input into 100kV DC output (positive or negative) effortlessly.
   
• Modular Design: Designed to connect multiple modules in series, enabling even higher voltage outputs.
   
• High Reliability: Encapsulated in solid epoxy to enhance durability and minimize corona formation.
   
• Handles up to 50mA Current: Built to support demanding high-voltage applications.
   
• Heavy-Duty Connections: Equipped with 50kV-rated DC silicone cables (20cm length) for secure and reliable input/output connections.
   
• System Compatibility: Perfectly paired with our half-bridge amplifiers and AC flyback transformers for complete system integration.

The High Voltage Multiplier requires an AC input voltage to generate a high-voltage DC output. For best results, use input frequencies above 20kHz to avoid damage and ensure efficiency. You will find that the multiplier reaches peak performance when you tune to the system's resonance frequency. Once achieved, you can adjust the output voltage and power by modifying the duty cycle and input voltage.

Important Note: While the maximum output rating is 100kV DC, we recommend limiting the output to 80kV to maintain an error margin and ensure long-term reliability.

High Differential Output Method: If you need to create an extremely high potential difference between two terminals, we recommend using the differential method. This involves driving two High Voltage Multipliers side by side—one for the positive output and one for the negative output—using a single AC source. By stacking two cascades of opposite polarity, you effectively double the potential difference while keeping the voltage to ground at half for each side. This configuration also provides better ripple performance and capacitor charging characteristics compared to a single long cascade.

Safety Disclaimer: High-voltage DC can be extremely dangerous if mishandled. This product is intended for experienced users who understand high-voltage systems and safety protocols. Always ensure proper insulation, avoid direct contact, and discharge residual energy after use.
