Transistor generators type PTG

Transistor Generators - PTG type

  • Output power up to 1MW
  • Frequency up to 80kHz

These are compact, modern products with very high durability and reliability of operation. The generator system itself works on the basis of a current inverter and is powered by a thyristor three-phase voltage regulator. The generator is a full-bridge inverter built with IGBT type transistors whose load is a parallel resonant circuit. Switching on the generator does not require a starting device, and the regulator operates because of the voltage or current or power settings.
