Variable High Frequency AC Power Supply

I'm in need of a professional who can help me build an adjustable/variable high frequency AC power supply, with the specifications listed below. He can of course source from existing products in the markets as long as he has fully carried out tests of their excellent functionality.

1. Power :1KVA
- Wave Type: pure sine wave or modified sine wave
- Voltage Output:220V
- Frequency range: 5Khz to 1Mhz

2. Power :2KVA
- Wave Type: pure sine wave or modified sine wave
- Voltage Output:220V
- Frequency range: 5Khz to 1Mhz

3. Power :5KVA
- Wave Type: pure sine wave or modified sine wave
- Voltage Output:220V
- Frequency range: 5Khz to 1Mhz

This power supply will primarily be used for laboratory experiments, so reasonable precision and reliability are key.

The control interfaces required are:
- A digital control panel for precise adjustments or Manual control options for hands-on operation

I am open to both pure and modified sine wave types for the power supply.

Ideal candidates for this project should have:
- Extensive experience in electrical engineering and power supply design
- Familiarity with laboratory equipment and requirements
- Ability to create user-friendly control interfaces

The power supply should employ air cooling mechanisms.
