Switch Mode technology when applied at high power levels is still an uncommon art. Around the world, RTP is one of only a few centres of excellence where this art, skill and experience is to be found.

RTP designs some of the world's most compact high power DC plants.

RTP has led the market in the introduction of the following features:-

• Microprocessor control of all external and internal management parameters
• Fan speed control and fan monitoring
• Battery charging current limiting
• Rear mounted connections for fool-proof installation
• Global set-up of parameters via supervisory/control unit
• “Plug & play” rectifiers which require no skill to exchange modules
• Battery cell voltage monitoring integrated into supervisory unit

Some technological innovations include:

• Use of IGBT/MOSFET combination in high power applications
• Development of lossless snubber and clamp
• Series/parallel connection of primary converter to achieve high/low voltage operation
• with a single transformer
• Noise cancellation techniques to reduce the size of filters

The following patents are held by RTP:

• Lossless Snubber for High Frequency Switching Power Converters
• True 3-phase switch mode rectifier
• Regenerative Clamp for Secondary Circuits
• Wide Bandwidth AC/DC Converter (pending)

RTP has developed rectifier models for the DC Power Systems industry since 1992.
