Reference Design For Single Plate Induction Cooktop

Its low-cost and low-component depend system additional enhances its enchantment, making it a useful addition to the equipment market.

The only-plate induction cooktop is an important equipment in fashionable kitchens, identified for its effectivity, precision, and security. Using electromagnetic induction, it instantly heats cookware, making certain speedy cooking whereas minimizing power loss. This know-how gives a number of benefits, together with exact temperature management, which is essential for varied cooking methods from boiling to simmering. Moreover, induction cooktops are safer than conventional stoves, as they continue to be cool to the contact and scale back the danger of burns. These options make single-plate induction cooktops preferrred for each house {and professional} kitchens, enhancing cooking efficiency and power effectivity. They’re additionally appropriate for inductive heating purposes past the kitchen, equivalent to in room and water heaters, resulting from their environment friendly and adjustable energy management capabilities.

The AS048 2100W reference design by Microchip Expertise is single-plate induction cooktop is a high-efficiency, high-reliability design using the iW248 sensible IGBT driver and controller single-chip ASSP. This modern design permits customers to regulate energy in ±10W increments, making it preferrred for exact cooking circumstances, equivalent to simmering. The iW248 sensible IGBT driver and controller single-chip ASSP ensures excessive effectivity and reliability, providing the flexibleness to regulate energy in high quality increments for varied cooking wants. The RL78/G15-based HMI card encompasses a low pin depend, a number of matrix switches, LED indications, and a 7-segment show. A sturdy capacitive contact sensing unit (CTSU) ensures dependable operation even in moist circumstances. 

Enhanced Security, Safety, and Price-Efficient Design

Enhanced security and safety are offered by over-temperature detection built-in utilizing three detrimental temperature coefficient resistors (NTCs). The design additionally incorporates AC enter, IGBT voltage spike detection, and present sensing through the iW248, enabling a quick safety response. Adjustable overvoltage cutoff and restoration register settings supply added safety and reliability. The built-in ASSP design reduces the general price and part depend, making the system extra economical and compact. The cooktop operates in both fixed present or fixed energy mode, decided by VCE voltage detection, with patented low-power know-how permitting high quality energy adjustability essential for sustaining simmer circumstances. The design helps three-temperature detection choices with adjustable settings, catering to varied cooking necessities. 

This reference design is good for house home equipment, providing precision and reliability for on a regular basis cooking, and is appropriate for skilled kitchen tools the place exact temperature management is essential. It can be tailored to be used in inductive heaters, benefiting from its environment friendly and adjustable energy management for room and water heating purposes. It’s powered by the iW248 sensible IGBT driver and controller, supplies a sturdy, environment friendly, and versatile answer for contemporary cooking wants. With its superior HMI options, enhanced security mechanisms, and versatile efficiency modes, this design meets the calls for of each house {and professional} kitchens, in addition to inductive heating purposes.
