Brushless Multiphase Self-Commutation Control (BMSCC) And Related Inventions

Abstract

The Brushless Multiphase Self-Commutation Controller or BMSCC is an adjustable speed drive for reliable, contact-less and stable self-commutation control of electric apparatus, including electric motors and generators. BMSCC transforms multiphase electrical excitation from one frequency to variable frequency that is automatically synchronized to the movement of the electric apparatus without traditional estimation methods of commutation and frequency synthesis using derivatives of electronic, electro-mechanical, and field-oriented-control. Instead, BMSCC comprises an analog electromagnetic computer with synchronous modulation techniques to first establish magnetic energy and then dynamically share packets of magnetic energy between phase windings of a multiphase, position dependent flux, high frequency transformer by direct AC-to-AC conversion without an intermediate DC conversion stage.

I claim: 
     
         1 . An electric vehicle power train system comprising at least one electric machine system connected to a high frequency power distribution bus, wherein said high frequency distribution bus is selected from a group consisting of single phase AC and multiple phase AC;
 wherein said power distribution bus has short circuit detection and soft switching means;   whereby said power distribution bus can be tapped for AC power at least at one location along said high frequency distribution bus.   
     
     
         2 . An electric vehicle power assistive system comprising at least two electric machine systems, wherein each of said electric machine systems is controlled independently;
 wherein each of said electric machine systems independently drive alternate axles involved with steering said electric vehicle;   wherein independent control of torque between said electric machine systems provide power assist selected from a group consisting of steering, braking, and stability further selected from a group consisting of fixed and variable control.
