QUESTION: Is it plausible to test power, out of aircraft, a mostly solid state device ie Microwave Oven? Can a VFD be programmed to run with inverter circuits. If so, 3 phase + ground output of VFD is 4 wire load compatable? PHOT0 1 vfd
POWER SOURCE, VFD = 1.5kw 1ph to 3ph, Chinese manual only, seller mistake
LOAD, Aircraft Microwave Oven = 1.5kw 115v 4 wire 3ph 380-600Hz power requirement
BUDGET $1000~ yes you can spend $20,000 for a ground support generator
Load design, aircraft microwaves have a entirely different primary power design. 3 phase 400hz power is fed thru a RFI line filter for each phase. This power then goes thru power conversion mosfet circuits and AC to DC inverters. Anything to avoid using a transformer. Only one conventional transformer is used to power the magnatron filament, not counting the switching xformers on the boards.
UPDATE METHOD to power 115vac @400hz 1500va Oven Super advice. Yes the maximum power consumption is 1500W, the intent was to power up and check the brains of the unit with the 1500va VFD and not cook. I have now repaired a 1968 Unitron frequency converter. Producing 2000vA 3ph-200ac in /2 ph-115 out @400hz. The QUESTION now is the oven requires 3ph at 115v, I have only produced the 400hz variable. Im already fooling the frequency converter with "fake" 3ph (3phase motor/cap running off 1ph 220v). Based on the schematic attached, how would it be possible to make "fake" 115vac power?
This is the 3ph Power management schematic.
