Abstract: ESBTTM is composed of a high voltage bipolar transistor and a low voltage power MOSFET with a low on-state resistance. The two devices are connected by a common generation common base amplifier (CASCODE) structure.The main advantages of this solution are fast turn-off and low pressure drop during conduction.Because of these characteristics, the ESBTTM series represents an ideal solution for conventional switching applications with full or quasi resonant converters. 1 the Introduction The recently launched ESBTTM (Emitter Switch Bipolar Transistor) is a new line of electrical actuators that are a valuable cost effective solution for applications requiring high voltage and high switching frequencies.This...

Abstract: The load of the induction cooker is a boiler that is used to heat. The changing of the size and the material, resulting in the main circuit with electrical resonance of induction cooker flap the frequency variety, often will cause the damage of the power tube IGBT as external pressure. so the adjustment of the exportation power for induction cooker is necessary when have variety the pot ,and have a method to examining the electric circuit. The former examining electric circuit contain shortage, this text put forward a kind of examine method about pot of induction cooker according one-chip...

A good electronic product, in addition to its own functions, circuit design and electromagnetic compatibility (EMC) design level, product quality and technical performance indicators play a very key role.Modern electronic products, more and more powerful functions, electronic circuit is more and more complex, electromagnetic interference and electromagnetic compatibility has become an urgent need to pay attention to and solve an important technical problem, developed countries have electromagnetic compatibility as a non-tariff trade barrier to protect their market.     Design of EMI filter The basic use of filtering technology is to select signals and suppress interference.Filter is a way to compress the spectrum signal...

Electromagnetic induction is widely used in cooking all over the world Cooking.Between now and 2018, the induction cooker market will Grew at a compound annual growth rate of 6.83% (according to industry TechNavio).However, induction cooking Kewlinary ways are unique to each region Development path is very different.This article will take a look at the accuracy resonant cookers have different equivalent circuits and involve different use the coil properties of the pan material. Figure 1: Quasi resonant circuit   There are several induction cooker circuit topologies, each one for a particular region of the world.In Europe, more Unit, half - bridge resonant stoves are becoming more and more common. But in Asia...

Is Induction Cooker Energy Saving Induction cookers don't consume too much power.Induction cooker is a large user of electricity, but because of the heating up quickly, the price of electricity is relatively low, calculated, the cost is cheaper than gas, natural gas. Induction cooker system uses the coil to generate the alternating magnetic field of low frequency (20~25KHZ) under the action of the control circuit, and a large number of dense eddy currents are generated through the magnetic conduction (iron) pot, and the induced current is converted into heat to heat food, with high energy efficiency.Use iron, special stainless steel or iron...

Precautions for the use of induction cookers 1, Induction cooker must be cleaned and checked before use If the induction cooker is not used for a long time,when re-enabled, be sure to remember to clean and check. It is best to wipe the furnace surface with a wrung cloth, but also to check the induction cooker power supply. And repair or replace any damage in time. 2. Place it flat If the tabletop is uneven, the gravity of the pot will force the furnace body to be deformed or even damaged. If the tabletop is tilted, the microshock generated by the pan can easily cause the pan...

What is an Infrared Cooker Induction cooker plays a very important role in our life, but with the increasingly high requirements of people's use now, there is a better electrical appliance, that is, infrared cooker. I believe that many people do not know what is infrared cooker. So am I before i sold infrared cooker. I just know induction cooker and only use induction cooker before. Infrared cooker look similar to induction cooker on the surface but they are much different inside. The infrared cooker is a kind of stove equipment which converts electric energy into heat energy by using electric heat flux effect. It simply heats...

The working principle of Induction cooker In recent years, hot pot has been favored by countless young people.Because people is opposite the demand of chafing dish is larger, so most people can buy induction cooker to cook chafing dish by oneself in the home to eat.So, what is the working principle of induction cooker? In fact, the work of the induction cooker is mainly using the principle of electromagnetic induction to heat food.The furnace surface of the induction cooker adopts a heat-resistant ceramic plate. When alternating current is used, the coil below the ceramic plate produces a magnetic field, and then the...
