In an induction cooking apparatus, an electrostatic shield is interposed between the work coil and the location of the cooking vessel upon the sheet forming a cook top to reduce the capacitive coupling between the coil and the cooking vessel to accordingly reduce the voltage between the vessel and ground.

Cooking vessel capacitive decoupling for induction cooking apparatus

An induction heating coil assembly including a flat induction coil wound from a glass-braid-encased multi-wire conductor retained on a rigid asbestos-cement support plate by a number of radially-extending metal retainer clips snapped into openings in the support plate. A shorted turn of heavy copper wire encircles the heating coil to confine its magnetic field and act as a coil-proximity spacer in cooperation with the underside of the horizontal glass panel member that forms the pan-support surface of a smooth-top range. Brackets of electrical insulating material provide support for the coil support plate.
