Max output current is less then 0.2A? What settings precision do you mean? What isolation rating (primary-secondary) must be? Clean sinus output? (or PWM approximation is enough?) Size? Weight? Climate grade? Dou you need indication of output or just simple trim?

What are you actually trying to do? Variable Speed Drives are fairly standard devices these days and there are many available designs. Most have the same or similar input to output voltages and power. Couple of odd things in your bid you need to clarify. The input power seems very very very small. 5V 4A Dc is only 20 watts. Is this correct? Why or how do you think you can covert 5V 4A into usable controllable 3phase power? In most variable speed drives you CANNOT have input Power this low. The other odd thing is 2000Hz - most 3 phase motors are designed of 50Hz. Higher quality motors can go up to 200Hz which for most stadard motors means about 6000rpm. So why are you looking to spin up to 60,000rpm. What are you actually trying to do????
