AC-AC Inverters

  • Example of system structure
  • Example of structure with internal inverter

Our AC-AC inverter that we developed is a specialized component specifically for an engine-generator. The inverter features a driver for the electronic governor that controls the engine speed and does not require the customer to use an engine control ECU, thus helping downsize the footprint.

2 kVA Models

Features

AC/AC inverter first converts the three-phase AC energy, from the permanent magnetic generator connected to the engine, to a direct current. Then, the inverter outputs a sine wave.

AC voltage (3 Φ input) → DC voltage → AC voltage (constant voltage)

However, our AC-AC inverters can also be set up and used in parallel operation with our CPU-based digital control.
In addition, the structure of our AC-AC inverter features a solid mold design that is machined and that takes into account outdoor use. It is not only able to withstand dusty or dirty conditions, but also offers high reliability that can handle engine vibrations.
