DAT210 – Digital Auto-Tune Inverter
The DAT210 is a new Microcontroller design that automatically determines the optimum system operating
frequency (resonance). Years in the making, this technology will, for the first time, make high-efficiency self
optimizing systems available to everyone. This single-phase inverter provides a linear means to adjust corona by
using Pulse Density Modulation (PDM), with frequencies up to 30khz. This control scheme allows the inverter to use
the full potential of the IGBTs by reducing the usual high-frequency switching losses. Automatic buss-voltage
compensation stabilizes the output as power line conditions change. PTI has specifically designed transformers to
mate with the DAT210, thereby providing a complete high- voltage solution
Applications:
 Ozone system variable-frequency voltage drive and Pulse Density Modulation.
 Non-thermal plasma or cold plasma systems.
 Applications requiring good plasma coverage at extreme turn down, such as 1%.
 Corona Treatment and Static Eliminator systems.
 High-frequency, high-current supplies for laboratory use.
 DC to Single-phase output conversion for crane and gantry lighting.
Features:
 Microcontroller design provides unprecedented control integration. Formerly unmanageable in large systems,
automatically tuning maintains maximum system efficiency and holds power constant as system conditions
that effect performance may drift.
 Selections for full automatic system tuning, semi-automatic and manual modes.
 Advanced power control via Pulse Density Modulation (PDM) yields linear power (Ozone) output vs. command
signal, even at high turn-down. This is only possible when PDM is used.
 Extensive two tear fault enunciation maximizes up-time and simplifies service diagnostics. Latched
fault indicators retain fault status until serviced.
