Description

Induction range for vehicle The present invention relates to an induction range for vehicles, and more specifically, to an induction range for vehicles that allows water to be boiled or simple food to be cooked conveniently using a low-voltage power source inside the vehicle. Recently, due to restrictions on indoor activities following the COVID-19 pandemic, the number of people enjoying outdoor activities has increased significantly, leading to a surge in popularity for various outdoor activities such as camping and car camping. In particular, the rise in campers and car campers who travel by vehicle to spend time in nature has caused a rapid increase in demand for various electronic devices that can be conveniently used inside a vehicle. Since such devices enhance user convenience and make outdoor life more pleasant, functional and efficient equipment that can be installed in a vehicle is essential. Among these, there is an increasing demand for cooking appliances used to boil water or prepare simple meals during camping activities. However, since vehicle cooking appliances generally rely on 12V or 24V power from the vehicle's battery, issues with stable operation may arise. In particular, induction ranges require the generation of high-efficiency magnetic fields due to their electrical characteristics; however, when using low-voltage power sources like vehicle batteries, insufficient voltage can hinder the smooth generation of magnetic fields, potentially leading to performance degradation. Furthermore, prolonged use may result in electrical noise, or there may be risks of safety accidents or fire due to battery overload. For these reasons, there is a growing need for induction circuits that can safely and efficiently utilize vehicle battery power. A low-voltage induction circuit equipped with safe power management functions can conveniently perform various cooking functions outdoors, and by effectively suppressing electrical noise that may occur during charging and operation within the vehicle, it can provide an environment where users can use the device with peace of mind.
