In this R & D, with a view to contributing to the mass introduction of renewable energy and electrification, we are developing circuits and control technologies for high-power converters. The converters are for

1) PCSs for wind power generation and solar power generation, etc.

2) The various power equipment installed in factories, large construction machines, ships and EVs etc.

Power converters can be increased in output power by connecting multiple small converters cascaded in series using multi-level technology. Such multi-level converters can output sine-wave voltages with low.

Specifically, the following technologies has been being developed.

  1. Circuit and control technologies to significantly reduce the size and loss of multi-level converters
  2. Circuit and control technologies to improve the robustness of multilevel converters
