These Class-D amplifiers can reach about 80% of higher energy efficiency as compared to analog class AB amplifiers. With a greater efficiency, it can promote reduction of electrical load on alternator and permit extra functions or speaker channels within standard dimension enclosures. EMI issues,cost and pc-board size confined the automotive class-D use for high-power booster amplifiers. To overcome these blocks,full-digital amplifier ICs can now permit famous in-car equipments to present powerful high-quality audio experience. It also improves audio performance of high-power boosters and also incorporates circuitry for continuous and undistorted playback in vehicles with stop-start engine technology. It can also be used in hybrid vehicles as electrical traction drives and combustion engine switch with different modes of operation.
