Appeal No. 98-0130 Page 2
Application No. 08/631,793
The appellant's invention relates to a power converter
having a magnetically coupled control. Specifically, first
(32) and second (30) circuit assemblies are mechanically
separable (figure 2) and include communicators (120, 121)
which are electromagnetically coupled by windings (40, 42) for
passing control information by modulating a carrier signal
(figure 8). An understanding of the invention can be derived
from a reading of exemplary claim 1, which is reproduced as
follows:
1. Power converter apparatus comprising
a transformer having galvanically isolated windings
defining a primary side and a secondary side of said power
conversion apparatus,
a switch for coupling power from a source on the primary
side via the transformer to a load on the secondary side,
a first circuit assembly having primary-side circuitry
galvanically coupled to a port for connection to an input
power source, said primary-side circuitry including a primary-
side communicator for sending or receiving control information
used in controlling operation of the power conversion
apparatus,
a second circuit assembly having secondary-side circuitry
galvanically coupled to a port for connection to a load, said
secondary-side circuitry including a secondary-side
communicator for sending or receiving said control
information, and
circuitry for passing said control information by
modulating a carrier,
