Induction Heating and Control System and Method with High Reliability and Advanced Performance Features
An induction heating and control system and method have enhanced reliability and advanced performance features for use with induction cooking devices, such as induction heating ranges. Enhanced performance is facilitated via the use of an induction heating system which integrates voltage management, power management, thermal management, digital control sensing and regulation systems, and protection systems management.

62 . A top for an induction cooker, the top comprising;
a temperature resistant, substantially rigid material for supporting a cooking container during induction cooling; and
a temperature resistant, substantially flexible material disposed proximate the rigid material; and
wherein the flexible material is configured so as to inhibit spilled liquids from contacting electrical circuitry of the induction cooker if the rigid material cracks.
63 . The top as recited in claim 62 , wherein:
the rigid material comprises at least one of glass and ceramic; and the flexible material comprises silicon rubber.
64 . The top as recited in claim 62 , wherein:
the rigid material is generally planar; and
the flexible material is generally planar and is in laminar juxtaposition to the rigid material.
65 . An induction cooker comprising;
an induction coil;
electrical circuitry for effecting operation of the induction coil;
a temperature resistant, substantially rigid material for supporting a cooking container during induction cooking; and
a temperature resistant, substantially flexible material disposed proximate the rigid material; and
wherein the flexible material is configured so as to inhibit spilled liquids from contacting electrical circuitry of the induction cooker if the rigid material cracks.
66 . The top as recited in claim 65 , wherein:
the rigid material comprises at least one of glass and ceramic; and the flexible material comprises silicon rubber.
67 . The top as recited in claim 65 , wherein:
the rigid material is generally planar; and
the flexible material is generally planar and is in laminar juxtaposition to the rigid material.
68 . A barrier for an induction cooker, the barrier comprising;
a heat resistant material configured to inhibit leaking of liquid thereby in the event that a support surface for cooking containers cracks;
wherein the barrier mitigates undesirable contact of the liquid with electrical circuitry.
69 . An induction cooker comprising:
a support surface for supporting cooking containers during cooking; at least one induction coil disposed generally below the support surface; a light disposed proximate at least one of the induction coils; and
a light driver circuit configured to cause the light to illuminate in proportion to the power provided to the induction coil to which the light is proximate.
70 . The induction cooker as recited in claim 69 , wherein an intensity of the light varies in proportion to the power provided to the induction coil.
71 . The induction cooker as recited in claim 69 , wherein the light blinks at a rate which is in proportion to the power provided to the induction coil.
72 . The induction cooker as recited in claim 69 , wherein the light mimics, at least in part, the glow of an electric burner.
