Minimal left-right symmetric intersecting D-brane model

open access: yes, 2017
We investigate left-right symmetric extensions of the standard model based on open strings ending on D-branes, with gauge bosons due to strings attached to stacks of D-branes and chiral matter due to strings stretching between intersecting D-branes.

An active circuit for cancellation of common-mode voltage generated by a PWM inverter [PDF]

open access: yes, 1997
This paper proposes an “active common-noise canceler (ACC)” that is capable of eliminating the common-mode voltage produced by a PWM inverter. An emitter follower using complementary transistors and a common-mode transformer are incorporated into the ACC,
