Which company has the highest share of energy storage bidirectional converters

What are the benefits of using bi-directional converters?

Bi-directional converters reduce peak demand tariff, reduce load transients, and provide V2G capabilities with quick power transfer direction changes. They also offer high efficiency (>97%) at power levels up to 22KW. These converters use the same power stage to transfer power in either direction in a power system.

What is a bi-directional converter?

Bi-directional converters use the same power stage to transfer power in either direction in a power system. This helps reduce peak demand tariff, reduces load transients, and enables quick changes in the direction of power transfer. They have high efficiency, up to 97% at power levels up to 22KW.

What is a bidirectional DC–DC converter?

In addition, to realize energy recovery, the bidirectional DC–DC converter is required between the power battery or SC and vehicle bus to realize the flow of feedback energy. Therefore, the bidirectional DC–DC converter is the key component of HESS. It determines the performance of HESS and further affects the performance of the powertrain of NEV.

What are the applications of power conversion system?

Power conversion system is widely used in power system, rail transportation, military industry, petroleum machinery, new energy vehicles, wind power generation, solar photovoltaic and other fields.

What are the research directions of dc-dc converters?

The research directions of DC–DC converters are prospected from some perspectives. New energy vehicles play a positive role in reducing carbon emissions. To improve the dynamic performance and durability of vehicle powertrain, the hybrid energy storage system of “fuel cell/power battery plus super capacitor” is more used in new energy vehicles.

What is H bridge bidirectional DC–DC converter?

The H bridge bidirectional DC–DC converter has a less number of energy storage elements and is easy to achieve high power density. A high voltage conversion ratio can be obtained when the duty cycle is close to 0.5. However, the large number of switches leads to the relatively complex control strategies and circuits.
