Invention Reference Number
Induction cooking offers energy efficiency and precision, but traditional systems are limited to ferromagnetic cookware. This new technology overcomes that limitation, enabling the use of a wider range of metal cookware, including non-ferromagnetic materials, without sacrificing performance or control. It expands the accessibility and flexibility of induction cooking for residential and commercial applications.
Description
This novel induction cooktop design introduces a system compatible with all-metal cookware. It uses a variable impedance matching transformer and a full-bridge inverter operating at adjustable frequencies. By tuning both the transformer tap settings and the operating frequency, the system can accommodate metals that traditionally pose challenges for induction cooking due to their electrical or magnetic properties. The innovation allows precise heat control while maintain safety and energy efficiency, broadening the usability of induction technology without requiring specially designed cookware.
Benefits
- Enables induction cooking with a wider variety of metal cookware
- Enhances energy efficiency and cooking precision
- Flexible operation using tunable frequency and impedance matching
Applications and Industries
- Consumer and commercial kitchen appliances
- Energy-efficient cooking solutions
- Smart kitchen and connected home technologies
