Self-oscillating converters

The next question is, is the efficiency being lost in the switch If so, there could be many reasons for that. A switch could be lossy simply because its drive is inadequate. Early self-oscillating converters (ringing choke oscillators) were extremely lossy because the drive would slowly droop to the point where it just couldn t sustain itself and then the switch would turn OFF. Modern self-oscillating converters have improved tremendously on this, and you can even find full-fledged multi-output PC power supplies that don t have a single... [Pg.222]

For the special case of the self-correlation function (n=m) B n,n,t) reveals the mean-square displacement of a polymer segment. For large p the cos in Eq. 3.16 is a rapidly oscillating function which may be replaced by the mean-value 1/2. With this approximation we can convert the sum into an integral and obtain ... [Pg.28]
