Working of D.C Generator As explained before the D.C generator converts mechanical energy into electrical (D.C) energy. The generator is usually coupled to a prime-mover. The prime-mover may be a diesel/petrol engine, or a turbine depending upon the rating and application of the generator. The prime-mover converts some sort of energy (diesel/petrol/water/steam/gas etc.) into mechanical energy. This mechanical energy is supplied to the generator (i.e. generator input). Working of D.C Generator If the generator is very small for commercial purpose i.e. for a shop or small work shop or cinema etc. the prime-mover is a diesel engine. If the generator is very big like in power stations then the prime-mover will be a turbine. Again depending upon the resources the turbine may be a water turbine, steam turbine, gas turbine etc. When the prime-mover output is given to the generator, the generator armature starts rotating. Usually the poles on the yoke are made of permanent magnets. Therefore, ...

Features 1 watt per channel with 8-ohm load Max. efficiency » 80% with 8-ohm load at 5 volts Filterless Digital gain control Build-in depop circuitry Error protection for short circuit and over-temperature Mute (shutdown) current < 1µA typical Low operating current (4mA at 5 volts without load) TSSOP 24L package available  General Description The AP130 is an oversampling class-D power amplifier for  stereo audio applications. It provides high power-efficiency for filterless 8-ohm load. Build-in depop, mute and gain control features simplify the applications. BTL (Bridge-Tied-Load) configuration delivers up to 1 watt into 8-ohm load per channel at 5-V supply voltage. It allows direct coupling of the power signal. Reliability is improved through over-temperature and short circuit protections. The class-D power amplifier enables high efficiency applications for portable devices.
