The Bubba Pure Sine wave oscillator 50Hz 3Phase with turn on button ,This can by replaced with 1 TTL pulse ( The normal automatic starting part of the Bubba oscillator circuit create a difference between the positive and the negative wave form voltage from 0volt ) ,And the 3Phases converter with 3 independent outputs each 120° from another ( 3Phase pure sine wave AC ) the first output ( 1Phase ) is synchronous with the Bubba oscillator output but capable to drive another input without affecting the Bubba oscillator frequency and also it Boost up te output voltage ,2Phase and 3Phase are divided in 2 steps ,The first step move the wave position 60° and the second step move it another 60° and also boost the output voltage ,The potentiometer's set output voltages 1Phase most by set first 2Phase second and 3Phase at last ,Onse set changing 1Phase output voltage makes all 3Phases voltages change together at same previous difference from 1Phase ( no previous difference from 1Phase means all voltages move the same together ) ,The output voltage range is from input voltages ( Bubba oscillator ,1Phase and 2Phase outputs ) to Maximum amplifiers input power voltages e.g. +15Volt and -15Volt ,Warning it take few seconds to stabilizing the 3Phases on slow motion, Onse te 3Phase positive and negative wave voltages are te same its all done.
