DC-AC Inverter Platforms

2_5kVA_INV

Creative Power specializes in the development of custom DC to AC inverters for both on-grid and off-grid applications.

In addition Creative Power has developed grid connected bidirectional inverters in both single and three phase configurations. These offer the flexibility of bidirectional power flow for applications such as battery chargers or microgrid power supplies.

Creative Power specializes in the development of custom solutions to meet specific customer requirements. This is achieved through Creative Power's extensive "building blocks" of controllers and power stage designs. Contact us if our listed products don't quite meet your requirements.

The following are some examples of products that Creative Power has developed for customers.

2.5kVA Bulk Inverter

2.5kVA
  • Input Voltage: 90-140VDC + 15% ripple
  • Output Voltage: 110VAC/230VAC ±5%, 50Hz
  • Rated Power: 2.5kVA @ 0.8pf
  • Efficiency: >92%
  • Galvanically Isolated
  • Naturally Cooled

The 2.5 kVA inverter uses MOSFET and IGBT technology arranged in a double conversion topology, with galvanic isolation, to convert a nominal 110V DC input supply into either a 110V or 240V AC single phase 50 Hz output supply. The unit was designed for underslung mounting on a railway coach, with an enclosure that could withstand shock impacts. The unit is naturally cooled and is used in environments subject to extreme thermal cycling and prone to monsoonal flooding. The unit was manufactured by a third party company to CPT's design.

25kVA Static Inverter

25kVA
  • Input Voltage: 90-170VDC
  • Output Voltage: 415VAC ±5%, 3 Phase 50Hz
  • Rated Power: 25kVA @ 0.8pf
  • Efficiency: >93%
  • Naturally Cooled
  • Non-isolated

The Inverter uses IGBT technology to convert a nominal 110 V DC supply into a 415 V AC, 3 phase, 50 Hz power supply for air conditioning units and associated loads, such as coach fans and lights, water raising apparatus, evaporator fans, condenser fans, compressors etc., that are installed in conventional coaches in international markets.

The 25kVA Static Inverter is designed and manufactured for underslung mounting on a railway coach, with an enclosure that could withstand shock impacts. The unit is naturally cooled and is used in environments subject to extreme thermal cycling and prone to monsoonal flooding. The unit was manufactured by a third party company to CPT's design.

5kVA Grid Connected 3 Phase Inverter

5kVA
  • DC Voltage: Operating Range 550 - 750VDC
  • AC Voltage: 400VAC ±15%, 3 Phase 50Hz
  • Rated Power: 5kVA @ 1pf
  • Full Power Factor Control (leading and lagging)
  • Efficiency: >97%
  • Fan Forced Cooled

The 5kVA Inverter Module is a grid connected 3 phase inverter for use on microgrids. The Inverter Module interfaces directly to the range of DC/DC Converter Modules available through Creative Power.

The Inverter has an isolated RS485 Modbus interface that provides bi-directional real and reactive power flow control.
