Simple Systematic Power Booster Wiring diagram Schematic

This is a Simple Systematic Power Booster Circuit Diagram. The Power Booster solves the power distribution problem in a CATV network caused by high resistance and low energy-efficient. This power booster functions as a high-efficiency `power multiplexer` or, if you supply an external signal-source, as a high-power linear amplifier.

If you want to drive a load with a high-power square wave, the schema simply draws power from two external power sources, VI and V2, alternately. In this mode, the schema`s power-handling devices function as switches, dissipating minimal power. The RC time constant of the integrator, IC1, determines the schema`s oscillation period. If you supply an external drive waveform, the schema functions as a linear amplifier, and, consequently, inherently dissipates varying portions of that power. 

The power amplifier is stable for gains > 15. Diodes D1 and D2 limit the FET`s gate-voltage swing to less than 15 V. D3 is a dual Schottky diode that protects the FETs from short diagram between the two supplies, VI and V2, through a FET`s parasitic diode. With D3 in place, you can choose either power channel for the higher voltage input, lb drive the FETs, Q5 and Q6, at switching frequencies greater than 1 kHz, you will have to use gate drivers for them.
