Smart Transformer for DC Power

The Past: DC power only used for long distance, because DC substations are too costly
New Opportunity: Varentec Smart Transformer in DC mode is more efficient, and lower cost

Moving electricity as DC is more efficient than AC along power lines. Historically, for long distances the benefits of line efficiency could not overcome the high cost of DC substations. Now, it is possible to have both high efficiency and lower cost with the Varentec DC Smart Transformer system for electricity transmission.

Versus competitors

• - lower cost (25-40%)
• - uses half the space
• - no AC transformer

• - 4-8% more efficient
• - can take AC or DC input
• - higher power quality

Benefits to the Electric Grid Using Varentec DC Transformer
- Connect remote industrial facilities that seek to stop using diesel generators
- Convert existing AC power lines to gain 2-fold increased power line capacity
- DC cables go underwater, and underground to solve overhead right-of-way issues
- Multi-input Smart Transformer can simultaneously manage AC and DC power flow

Long Distance Electricity Transmission Using Efficient DC

In cases where an energy source is a long way from where the energy will be used, DC transmission offers advantages over AC transmission. DC offers higher transmission efficiency and lower cost of transmission lines (and eliminates reactive power issues). The Varentec DC transmission offers greater efficiency, at a lower cost, than other DC systems - to get more electricity to the destination.

Targeting medium power applications in the range of 5MW to 100MW, and power generators that operate over 10kV, Varentec offers a compact solution that does not require a conventional AC transformer. The power conversion and transformation are completed in one innovative unit.
All other competitors doing DC transmission or distribution must use a large conventional AC transformer together with a DC converter - we combine the two into a single, compact, high efficiency unit.
