Automotive electronics include modern electric power steering, HEV main inverter, central body control, braking system, seat control, and so on. Medical Electronics. Application of solid-state devices such as diode, silicon-controlled rectifier (SCR), thyristors, gate turn-off thyristors, TRIAC, bipolar junction transistor (BJT), Power MOSFET and so on for control and conversion of electric power is called as power electronics. Sensors are placed on t… Limitations can be overcome by using a wideband gap semiconductors like silicon carbide with a high-operating temperature that allows placing the circuit near high temperature location. Medical Electronics is a broad field. bioelectric phenomena in … The need to control engines of automobiles originated in automotive electronics for proper controlling and conversion.

SMPS concept is based on the power electronics devices such as semiconductor devices that operates in an on state that has zero voltage and an off state that has zero current during this state theoretically with 100% efficiency. It has two or three times higher thermal conductivity than silicon, which will eliminate need of big copper blocks and water jackets. Less bulky and small-sized power electronics based converters are used for high frequency switching as these switches are capable of operating under high switching frequencies. (from: Gene Nam June Paik, one of the pioneers of the field of electronic art, makes this distinction very clear by commenting on "electricity" and "electronics": "Electricity deals with mass and weight; electronics deals with information: one is muscle, the other is nerve." This conversion of AC to DC can be done by the application of power electronics converters called as rectifiers. This is due to power train system of automotive electronics with an engine or internal combustion or motor as one of the subsystem operating with high temperature exceeding 125 degrees Celsius. These topologies are classified as isolated and non-isolated topologies which are adopted in power train systems. We are living in an electronic era where machine robots are capable to do human work with more ease and high efficiency. Application of power electronics in automotive applications plays a major role in controlling automotive electronics. The power train systems of HEVs, electric vehicles and ICE need the following SMPS conditioners such as: There are different DC to DC converter topologies available which can be used based on the requirements. The application of power electronics is increasing with the advancing technologies in automotive electrical and electronics systems for improving the overall system efficiency with high operating temperature, increasing flexibility, reliability and to reduce the overall size of the circuitry. The frequently used alternator in automotive applications is Lundell or Claw-pole alternator, as it is suitable for the required emerging performance. Transparent smartphones will exist in the coming days, we can see through them and they may lead to the use of windows or mirrors in our home to be used as PC screens and TV monitors. We know that, the power can be stored in batteries only in the form of DC. Capsules and tablets contain wireless sensors that collect information from the body to diagnose. Extensive examples in the chapters are based on electronic circuit problems in biomed-ical engineering. Application of power electronics with components such as silicon-based power MOSFETs and IGBTs that are used as power electronic switches in the power train system of automotive electrical and electronic systems for reducing the overall size. Introduction to Electronics ii Dedication Human beings are a delightful and complex amalgam of the spiritual, the emotional, the intellectual, and the physical. Silicon carbide has high breakdown voltage and capable of switching at high frequencies with very less power loss which makes the overall size of circuitry very small.
