For companies that require to integrate an inverter stage into their product, we can supply quiet, efficient step up stages to provide a 200V/400/ (+/-)400V bus from which to run inverter bridges.
From basic inverter stages to drive a permanent magnet brushless 3 phase motor right thru to 20kHz controlled systems to provide clean 50/60/400Hz AC power (with no DC component) - we have done it.
Bi-directional stages where power can be imported and exported to the grid from a DC bus (up to 50kVA at present) have been developed also.
For remote area installations we have a very low RFI inverter; 24VDC to 230VAC, 3kWrun, 9kWstart, that allows loads from a single relay coil right up to a refridgerator starting load with no hassles. The design ensures that sensitive AM reception is not interfered with.
