The circuit shown in figure 1 meets these demands uately. It is a bridge version of the quite adeq PWM amplifier with an output power self-oscillating . in the order of 50 Watts audio amplifier has to be ower If such a high 1p2 V battery, one of the following supplied from a possibilities may be chosen: The amplifier operates at 12 V in combination 1. with a low impedance load. The amplifier operates at 12 V and a step-up 2. voltage so that the amp output. (The converter may or may not include a transformer ). The advent of the power MOSF ET makes the third possibility especially favourable. The simplicity of the design is very apparent from the circuit diagram forpowerMOSFETsarea50Wattboosteranda showninfigure2.Infact,theentireconvertefrteisr power M.O2 in the car Due to the recent breakthrough in power-semi- conductor technology it has become relatively simple to construct high power equipment for use in the car.
