Why do we need bidirectional power supplies?
There’s a corresponding rise in the need for bidirectional power supplies to ensure the efficient transfer of power between various smart grid elements. In this blog, we’ll examine bidirectional power supplies, their applications, and how RECOM is helping our customers meet these new demands.
What are the benefits of bi-directional power design?
This article features the advantages and benefits of implementing bi-directional power design allowing full reversible power flow. The power system designer of just a few years ago might have wished for the means of simply transforming one DC voltage to another; today, that wish is fulfilled and the “DC transformer” is a reality.
What is a bi-directional Converter?
AC/DC topologies Bi-directional converters use the same power stage to transfer power in either directions in a power system. Helps reduce peak demand tariff. Reduces load transients. V2G needs “Bi-Directional” Power Flow. Ability to change direction of power transfer quickly. High efficiency >97% (End to End) at power levels up to 22KW.
How can a bi-directional power flow be accommodated?
The back-up battery, and the electro-mechanical flywheel would be examples where bi-directional power flow would be required. Differing voltage rails on both the supply (or storage) side can be accommodated simply by selecting the appropriate conversion-ratio module from the range available.
What is efficient bi-directional power conversion?
Efficient bi-directional power conversion can be applied to a range of different scenarios, that can be grouped together in a number of general divisions, as shown in Figure 2. The converter (isolated or not) can operate in its forward direction – conventionally a step-down, such as 48 V to 12 V: or in reverse, as a step-up.
Do EV charging stations need bidirectional power supplies?
Scenarios that call for bidirectional power supplies in EVs and EV charging stations include: EV supplying power back to the grid or to a microgrid in the home. EV charging station supplying power to an EV either from the grid or from stored energy depending on relative electricity prices.
