What are the specific advantages of transformerless inverters in fire fighting systems?
The advantages of transformerless inverters in fire emergency power systems (EPS) are mainly reflected in the following aspects:
Improve energy efficiency
Because the transformer is omitted, the transformer can directly convert the direct current to alternating current, thereby reducing the energy loss of 1% to 2%. This means that at a power of 500kW, a transformerless inverter can provide an additional 5kW of output.
Reduce wire costs on the AC side
The transformerless inverter converts directly to the available voltage, rather than the lower unipolar inverter AC voltage, and the AC current is reduced by more than half, thus reducing the wire cost on the AC end.
Reduce equipment size and weight
Since there is no isolation transformer, transformerless inverters are smaller in size and lighter in weight, giving power integrators greater freedom in installation and overall system design. This allows installation costs to be reduced, especially in tall buildings, where expensive high-rise wiring and reinforcement measures can be avoided.
Improve system reliability
Transformerless inverter technology uses a power optimizer (LineReactor) and smaller triangular filter capacitors, which are buffered by series resistors to improve the stability of the control system and reduce the interaction between parallel inverters. In addition, inverters with a single engine design reduce the number of components, thereby improving the reliability of the entire system.
Flexible parallel configuration
Multiple transformerless inverters can be connected in parallel without a transformer, directly using the power supply to achieve stable performance. This configuration offers numerous possibilities for site configuration, and because the current is lower than conventional inverters, the way to house inverters and transformers is more flexible.
Reduce footprint and cost
Transformerless inverters are about half the size of conventional inverters and can be converted directly to higher voltages, reducing the required floor space, transportation and lifting equipment costs. In addition, a standard switchboard connected to a transformerless inverter can supply power to the tracker without the need for a separate transformer, reducing the reactance component in the system for the most stable operating state.
Simplify installation and maintenance
The transformerless inverter is automatically and independently addressed over Ethernet, eliminating all interference problems and simplifying installation and maintenance.
Anti-islanding technology
The transformerless inverter uses a completely passive anti-islanding technology that does not interfere with the common voltage with VAR deviation, nor does it set other transients on the route, so it can achieve an efficient, smooth and stable power supply.
CONCLUSION
In summary, the application of transformerless inverter in fire emergency power system can bring many advantages such as energy efficiency improvement, cost reduction, installation and maintenance simplification, and is an important technical direction to improve the performance and reliability of EPS system.
