Converters Using SCR Thyristor Technology

ABP offers for the power supply of the furnaces converters using the well-proven thyristor technology.

The following advantages are arguments in favour of using thyristor converters as medium-frequency power generators:

• A good level of efficiency, also in reduced power operations, guarantees low energy costs.
• The converter can be switched on and off as often as needed without delays, accomodating short interruptions to production.
• Converters require minimal maintenance and have no components that wear out and work without any mechanical moving parts.
• The use of field-proven, conservatively rated electronic components results in a long useful life and high operational reliability.
• ABP parallel inverters adapt to all load conditions by means of electronic control without moving parts.
• Converters always present the supply system with a symmetrical, balanced load on all supply line phases. The power smoothly ramps up or down over a programmable period, providing a soft start, that eliminates inrushes and surges. Acceptable power quality is achieved by judicious selection of a 6, 12 or 24 pulse rectifier configuration.
