DC-DC buck boost converter is a conversion circuit using induced frequency inductors, switching.DC-DC converters dynamics was improved by using self calibrated preemptive current control. As, a result Preemptive concurrent control reduces capacitor size by 10x.DC DC buck converter with pulse width modulation.DC-DC buck converter with two step pulse width modulation was utilized for low power application by using delay, control line. Main motive of DC-DC buck converter with pulse width modulations obtains high linearity, high granularity. Conversion efficiency for Light load current was increased in buck converter by clocked hysteresis scheme. Power supplied to comparator was scaled to load easily. Conventional buck converter was integrated with LED to expand smart bulb. Main power from supply was decoupled by Non linear ramp control scheme preventing LED output flickering. Control scheme effectiveness was improved by small signal model. Three major characteristics of Light emitting diodes are improved lifetime, high efficiency, increased reliability, controllability. High brightness LED by multicell three phases was used for its lower cost. Heart beat was identified by using raspberry pi, system on chip with three stages in it namely Heart beat determination, Impedence, cardiography parameters. Accidents was restricted by this method.Overspeeding vehicles was identified was main goal of using complex proportional assessment method. Converting Rice husk into bio fuels was performed by thermo chemical processes. Rice hulk silica was utilized for fluorescent silica particles synthesis.
