Alternating current, has many drawbacks. In the delivery of power from the generating source to the consumer, as much as 80% of the originating power is lost through transformers and power lines - resulting in only 20% reaching the end users.

Direct current, in comparison, can reduce these power losses by an additional 20% to ultimately as much as 60%, resulting in two to four times more power to end-users from the same amount of power produced. In addition, a regulated direct current is free from surges, transients, and fluctuations present on today’s AC power lines. DC delivers “clean” power versus the “dirty” power typical of AC.

Another major feature is that DC can be stored in virtually any capacity by batteries, while AC cannot. This enables DC products to be portable as well as cordless, and allows operation during grid power outages. DC eliminates power factor from efficiency consideration resulting in better power utilization. Low voltage DC (under 50.4 volts) allows for much lower installation cost in both materials and labor while eliminating the fire hazard associated with high voltages. It is easier and cheaper to control uniformity, consistency and dependability of products or equipment that require consistent light level or regulated motor speed.

DC to DC voltage conversion - which was once not possible

with conventional transformers - is now accomplished electronically with dramatically greater efficiency than with AC-AC conversion. Today’s electronic technology allows low-power switching at efficiencies unheard of 30 years ago. Tomorrow’s electronic technology will do the same for high-power applications and will change the way power is produced and distributed.
