Reference Design For Single Burner Induction Cooktop

This reference design is a completely purposeful unit that achieves over 90% effectivity and consumes lower than 0.5W in standby mode.

Single-burner induction cooktops, obtainable in each drop-in and moveable fashions, are gaining recognition in properties, leisure automobiles, and eating places as a result of their effectivity and compact design. Fashionable single-burner cooktops function a low-profile design, excessive effectivity, and minimal standby energy consumption, making them a perfect alternative for a variety of purposes. To assist system designers handle design challenges and velocity up product growth, Microchip has launched a extremely cost-effective single-burner induction cooktop reference design. This reference design is a completely purposeful unit that achieves over 90% effectivity and consumes lower than 0.5W in standby mode.

Microchip’s reference design incorporates superior mTouch sensing options, permitting for exact performance even via 4 mm of Schott Ceran ceramic glass. This design incorporates a user-friendly interface with present settings prominently displayed through vivid 7-segment shows, guaranteeing clear visibility. On the coronary heart of this reference design is the PIC16F1619 8-bit PIC microcontroller. This microcontroller stands out as a result of its integration of Clever Analog options and Core Unbiased Peripherals (CIPs). These superior parts allow the microcontroller to effectively handle essential duties comparable to controlling a single insulated-gate bipolar transistor (IGBT) and the system fan. Moreover, it displays the temperatures of each the IGBT and the cooking floor, guaranteeing optimum efficiency and security.

The inclusion of CIPs considerably reduces the quantity of code required for operation. This discount in code not solely streamlines the design course of but additionally enhances the general effectivity of the system, making it extra dependable and simpler to keep up. Moreover, a separate PIC16F1939 PIC microcontroller is devoted to dealing with the person interface. This separation of obligations between the 2 microcontrollers ensures that each the purposeful and person interplay points of the design are managed effectively, contributing to a strong and user-friendly expertise.

Key options of the reference design embody a completely purposeful reference design with Core Unbiased Peripherals simplifying software program necessities, a low-cost single IGBT quasi-resonant circuit, zero-voltage switching on a single IGBT, over 90% effectivity (in comparison with roughly 39.9% for fuel and roughly 71.5% for electrical), standby energy consumption of 0.5W, most output energy of 1800W at 220V, energy enter choices of 110V or 220V at 50 Hz or 60 Hz, security algorithms together with pan detection and over-temperature safety, and dynamic fan management. It not solely simplifies the event course of for single-burner induction cooktops but additionally ensures excessive effectivity and reliability. With its superior options and sturdy efficiency, this reference design is a perfect answer for designers creating revolutionary and environment friendly induction cooktops for numerous purposes.
