LDM #334: Static Inverter PS285: reverse engineering and modification for 3-phases inverter.

This video shows the reverse engineering of the PS285 inverter. After understanding how this inverter works I show a simple method to synchronize the output signal to another inverter. Finally the video shows the new inverter which delivers two AC signals at 400Hz with 0 or 120° phase shift using two PS285 inverters. 00:00 - Intro 00:47 - Reverse Engineering Part 1: 400Hz sine oscillator 03:11 - Reverse Engineering Part 2: Output stage 04:02 - Reverse Engineering Part 3: Output voltage control circuits 05:16 - Modification for slave mode operation 06:08 - Slave Mode Test 07:38 - Modification for slave mode 08:28 - Phase shifter and final design 09:49 - Test Link to part 1: LDM #323: Aircraft Static Inverter EMP Electronics PS285: teardown and test https://youtu.be/2xIdZvDX5XA
