Patent ID: 8179168

Claim:
A free-running 3-phase pulse driver comprising: a free-running oscillator; 3-phase generating logic circuit having an input and three outputs, said input electrically coupled to said free-running oscillator, wherein said 3-phase generating logic circuit generates electrical signals on each of said outputs, said electrical signals separated from one another by 120 degrees of phase; at least three separate phase drivers, each of said phase drivers electrically attached to an output of said 3-phase generating logic; a divider taking an undivided signal (div 0 ) from said free-running oscillator and dividing it by 2 to produce a first divided signal (div 1 ), and dividing it by 4 to produce a second divided signal (div 2 ), and dividing it by 8 to produce a third divided signal (div 3 ); a logic circuit electrically coupled to said divider and said free-running oscillator producing a first output A=(div 3 ) EOR (div 1 AND div 0 ), a second output B=(div 1 ) EOR (div 2 AND div 0 ), and a third output C=(div 2 ) EOR (div 3 AND div 0 ).
