Renewable Energies can be intermittent depending on conditions. For example, when the sun shines you need to make power, but you don’t always need that power when it’s made, so you must have a way to store it as energy.

Direct Current Bidirectional converters are a key technology for energy storage because they can have multiple streams of DC power at varying voltages. Typically, these need to be integrated into a single current with a nominal voltage.

This Patent Forecast is divided into two groups: converters which convert directly (DC/DC) and converters which convert DC into an alternating current and then back into DC (DC/AC/DC).
