I. Introduction Nowadays the main concern of the world isto have advancement in technology without compromising with the greenerenvironment, hence this increases the demand of low power consuming equipmentthat motivates greener society. All the fields such as infrastructure,computer, medical and many do prefer to use energy and power efficient devicesthat are ecofriendly and motivates a low carbon society.
Various industry nowadaystaking initiatives for green cars, eco-friendly products, solar powergeneration and many more. The demands of such devices that reduces the CO2 emissionand power consumption is increasing day by day and because this the wind powerand solar power are accelerating. The European Commission(EU) introduced a newenergy-label layout that extended efficiency of the energy in the electronicsproducts. Many vehicles such as Hybrid Electric Vehicles(HEVs) are also fuelefficient hence contributing towardsreducing the emission of CO2 and moving a step towards a greener earth becauseeveryone desires eco-friendly products that is power and energy efficient. II. Microelectronics going GreenIntroduced in early 70s, themicrocontrollers were first use in electronic calculators and it was laterevolved into electro-mechanical.
Then the advancement in the electronics fieldintroduced microprocessors and then MCUs that is Microcontrollers for embeddedcontrols that are less commonly known semiconductor device that reduces thepower consumption byenergy monitoring and also do control the consumption of energy. In embeddedapplications there is a wide acceptance of MCUs because of its ease of use, lowpower, being small in footprint, adequate performance and low cost. In vehiclesalso, we find MCUs that controls engine and HVAC and so on. There is a wideacceptance of MCUs because of its self-containment and availability and ease ofuse. MCU is tiny piece of silicon that has been integrated with everything. MCUshave a strength in its programmability that is through on-board flash memorybut the introduction of Flash-based MCUs made their programmability at low powerwithin a very small foot print. III.
green controlMany researchers and analyst found thatthe motors that are used in washing machine, refrigerator, heat pumps,railroads, subways and so on do consume maximum electricity around 60% of thetotal power consumption. In the place of these motors we can use MCU that cancontrol the motors effectively and can minimize the power consumption. The MCUcan also control signal processing vector and inverter. This is because the MCUdirects the power devices regarding the current supply.
Use of MCUs in devicessaves around 30% of the total electricity. But along with the issue ofelectricity consumption problem, there is also a problem of CO2 emission. Manylarge industries have made strict regulations regarding this issue. So, thetechnologies should be according to it. MCU is the device that support suchtechnologies that can reduce the emission of CO2. MCU has developed a systemcalled flash Based MCUs that are evolving year by year.
Also, there has been ahuge and remarkable progress in HEVs and EVs technologies that are contributingto reduce the CO2 emission. MCUs are used in these HEVs and EVstechnologies. MCUs saves power through their widespread use and hence do serveas a core technology for which everything is going green.
Besides theachievement of low power consumption by MCUs, these MCUs are also used inconnecting various devices. Lin is also that kind of device that uses low-endMCUs and provides cost-effective networking solution to support LIN protocol. LIN(Local Interconnect Network) are used in sensors such as rain sensor, switches,light sensor and many more and is a sub-network of CAN (Controller AreaNetwork) which is an asynchronous in-vehicle-bus network.
CRITICAL FOR GREENAPPLICATIONWe use motors inmany applications. These motors consume a lot of power and energy. MCUs cancontrol such motors by inverter control and many more. MCU controls the powerdevice to supply current to motors. There has been a remarkable progress in theHEVs and EVs that are contributing towards a green society with low CO2 in thesurrounding. HEVs consumes power from a conventional internal combustion enginealong with an electric motor whereas EVs have no internal combustion engine.Both have a special battery with large capacity specially lithium ion that canbe recharged. MCUs used in HEVsand EVs integrates the function of motor control and also regeneration controlwhere by motor control MCU provides motive power for 3-phase motor throughpre-drivers and IGBTs and control regeneration by the motor that acts as agenerator that converts mechanical energy into electricity Thus MCU saves a lotof power by their wide spread applications.
CONCLUSIONThe advancement ofMCUs have led the industries towards the use of smart microcontrollers andthus, helped in reducing the power consumption and providing high performance.The applications of MCUs are increasing so rapidly that in future it wouldbecome a major part of the finely-meshed network all over the world. MCUs providedthe way for a smart controller that paves the way to a greener society.
