Power Amplifier TDA1514 , this power use the IC TDA1514 , minimum require voltage 12 Volt  and maximum voltage 30 volts DC. Power output maximum 100 Watt mono with 8 ohms impedance. this circuit is High output power amplifier with IC. See schematic below :

Two octave wideband amplifier (covering both the civil and military airbands between 100 and 450 MHz), equipped with two MOSFET devices, which is capable of generating 250 W of output power are given on this design procedures and measurement results report. One of the two octave wideband amplifier has to use the device s with the output capacitance reduced to the utmost minimum in order to achieve a good broadband capability. It was possible to obtain a respectable power gain of more than 10 dB throughout the whole band while applying PHILIPS’ BLF548 MOSFETs. The BLF548 is a balanced N-channel enhancement mode vertical D-MOS transistor in a SOT262 package. This device is especially designed for use in wideband amplifiers up to 500 MHz. 150 W nominal output power at a supply voltage of 28 Volts can be delivered by the transistor. The attainable bandwidth will exceed 300 MHz due to the low output capacitance. Notes 1. American Technical Ceramics type 100B or capacitor of same quality. 2....

This is a simplest circuit for 100 watt inverter for generating 220vAC from 12vDC. I say simplest because here in this inverter circuit a minimum number of components are used to design the schematic, which is quite difficult to make a circuit like this with further fewer components.   Simple 100 Watt Inverter Circuit Diagram This 100W inverter circuit works great for small loads like a fan or 2-3 bulbs/lamps. In this circuit as IC1 we used a CD 4047 IC to generate 100Hz frequency (180 degree out of phase). CD 4047 IC is from Texas Instruments. It is mostly used as Astable/Monostable signal generator device. In this circuit it is triggered as astable multivibrator by the capacitor C1 between the Pin 1 and 3 of CD4047. And VR1 is used to adjust the frequency of signal. Four 2N3055 transistors are used to amplify the pulse trains that are pre-amplified by two TIP122 transistors. There used three transistors for each side (half cycle), one TIP122 & two 2N3055 transistor to drive t...
