DVC Applications

Ocean Power Generation- Similar to wind power, ocean wave energy has expensive mechanical design issues when converting the ocean’s kinetic energy to useful electrical energy. Even more so than wind, ocean waves move at different speeds and in different directions from moment to moment. Converting this energy to a steady voltage and frequency output is even more complicated and costly than with wind turbines.

 

Again, because the DVC can convert an input of irregular voltage into a stable stream of output voltage and frequency, ocean wave energy conversion, a once complicated technology, becomes very simple and inexpensive. For example, one ocean wave energy conversion method uses an underwater buoy moored to the ocean floor. This, in and of itself is a very basic, straight-forward, low-cost mechanism. However, because the buoy bounces erratically in many different directions, the power becomes expensive and difficult to harness mechanically when attempting to convert it into a steady voltage output.

 

Currently, this technology uses the motion to pump water out of the ocean into a reservoir to create a stable environment from which to withdraw the energy. Here, the water is sent through a hydro-turbine gen-set to produce electricity. As a result, this design becomes more expensive than wind. Utilizing a DVC circuit can eliminate the majority of the complexity

 

and cost from this system. Instead of a pump, plumbing, reservoir, and hydro-turbine, the buoy can simply be tied into a linear generator. It can bounce in any direction and at any frequency. The DVC will convert the variable voltage to any steady output desired.
