The recent development call the DVC circuit claims advantage for a variety of storage devices. For example, PV solar cells, like lithium battery cells, are connected in series which limits the entire units performance to the lowest performing cell. If one cell goes completely out, the entire battery is unusable.
The DVC is said to be the first technology capable of handling and converting a full range of variable voltage on the fly to a constant DC or AC voltage and frequency output. It can also convert a constant input voltage to a variable output. This new device operates without transformers or coils, making it much lighter and significantly more compact than today’s transformers and inverters. For many uses, it can be reduced to the size of a silicon chip.The DVC circuit works by letting each cell discharge independently in parallel. This power is then switched within the DVC circuit to a series output. If one cell goes bad, the DVC can automatically adjust the voltage to compensate.
Furthermore, the DVC circuit increases the lifespan of the lithium battery, iteliminates the dangers of lithium explosions caused by putting current through a defective cell when connected in series.
Another use: Instant charge battery. Capacitors currently cannot be used as batteries because as the capacitor discharges, its voltage decreases. However, the DVC can stabilize this variable voltage to a steady, constant voltage output. By doing this, a capacitor can now be used as a battery, or in conjunction with a traditional battery.
The primary advantage of this is the ability to instantly charge the capacitor. Instead of waiting for hours, a capacitor DVC battery could be charged in seconds and minutes. This would make electric cars more appealing than current fossil-fuel cars. It would also make charging cell phones, laptops, power tools, and more, convenient.
Electric car breaking-system energy recapture- Currently, electric cars cannot fully take advantage of recapturing energy lost in breaking. This is because a battery cannot charge fast enough to capture the energy from stopping. Using a DVC battery could allow for most of this energy to be recaptured instantaneously.
Reduced size of electric generators and motors- Because of the dynamic nature of IAUS’s voltage controller, electric motors and generators can operate with more versatility and efficiency while requiring less copper windings. This will make motors and generators for applications such as robotics, power tools, transportation, machining, etc. much lighter and smaller.
“A prototype of this new voltage controller has been successfully built and demonstrated. From here, we intend to develop marketable products. With the right strategic partners, our next step could be achieved in a relatively short amount of time,” said Neldon Johnson, President and CEO of IAUS.
