DC to DC Power Supplies (Converters)
DC/DC Converter features transformerless architecture.
Press Release Summary:
Utilizing transformerless voltage conversion topology, 7.5 kW Charge and Add (C/A) DC/DC converter is designed for electric car applications - specifically for converting 48 Vdc into 240 Vdc to drive brushless DC motor. This step-up (x5 input voltage), adjustable (0 V to Max) converter weighs less than 10 lb and may be stacked in any number and connected in series to achieve higher output voltage.
Original Press Release:
DR/VSHolding Scheduled Delivering of a 7.5kW the First Kind of Charge & Add (C&A) DC/DC Converter
Louisville, KY - September 26, 2009 - Electronic Design & Research, Inc., today announced successful test of a new type of 7.5kW C&A DC/DC converter, patent application was filed two weeks ago. The C&A DC/DC is utilized a new topology of a transformer-less voltage converging.
The first field prototype was design to be used in electrical cars for converging 48VDC into 240VDC to drive a brushless DC motor. It is a step-up (x5 of an input voltage), adjustable from a zero volte to the maximum, highly efficient, weights less than 10lb, and low EMI. The converter is stackable, two or any number of them can be connected in serious for a higher output voltage.
We are designing a 50kW converter and will keep you updating. There is no limit how powerful converter can be. If you have an interest for 100kW or higher power converter, please send us an inquiry. That type of converter will definitely find applications in converting power from a fuse cell, photocell and low voltage batteries. It delivers a high-voltage, high-power pulse in a few milliseconds.
A DC/AC converter from 12VDC to 220VAC based on the same technology will be available in six months.
