DSP Based Solutions

There are many good reasons for a manufacturer to develop a replacement technology. However, these drivers often relate more to manufacturing, cost and competitive considerations than to the product's intrinsic ability to undertake the primary task for which it was designed.

While in some cases it may be acceptable to make compromises in absolute performance, especially when size and value for money are included in the equation, other applications require a more robust solution.

Traditional technology, in the guise of the transformer-based online UPS is, at power ratings sub 40kVA, being usurped by the latest advancements in transformer less UPS design.  The advent of sophisticated controllers/signal processors electronics and advancements in power electronics has allowed UPS manufacturers to produce ever more capable devices at lower costs.  DSP's have solved this high frequency PWM generation because of inherent math techniques at high speed.  Ramp plus actively engaged in developing HW/SW infrastructure to solve PWM algorithm required for these applications.

And, because the latest breed of transformerless online UPS dispense with conventional bulky and heavy transformers, they offer a highly compact and cost-effective solution for many modern power protection environments.

An average transformerless online UPS with a reasonable specification can provide adequate power protection for a wide range of critical devices. Because of the recent proliferation of transformerless UPSs, most customers will be able to find a suitable device within their budget, and which boasts a specification that appears to meet their needs.
