Optically isolated bias control circuit

   
   

Optically isolated bias control circuit which provides bias current for switching circuits. Invention is amenable to high speed switching control with instantaneously variable pulse widths and duty cycles. Invention can be operated from DC upward in frequency, limited only by the characteristics of the implementing electrical components and electrical interconnections. Complementary embodiments of invention provide high speed operation with minimal electrical charge flow. Solar powered embodiments of invention may be used to control the switching of high power MOSFET-based switching circuits.

O circuito de controle diagonal ótica isolado que fornece a corrente diagonal para o switching circuita. A invenção é amenable ao controle de alta velocidade do switching com larguras do pulso e ciclos de dever instantaneamente variáveis.
