... passes through the individual gate resistors (R20 through R24) and then combines into the BJT Q7. D6 is added to bypass R2 and provide sufficient base current for the BJT Q7 for rapidly turning it on. The VBEmax of Q7 is 5 V. D44 helps clamp the VBE of Q7 to ≈ 0.4 V when it is in the off state.

... Hence output follows the input. Fig 3.3.8 shows a biased clipper where the diode is reverse biased by V volt. In the positive half cycle it only starts conducting for voltage above V volts. Hence the circuit is clipped above V volts where the output is shorted. For input less than V volt, the diode ...

Islanding

Islanding refers to the condition in which a distributed generator (DG) continues to power a location even though electrical grid power from the electric utility is no longer present. Islanding can be dangerous to utility workers, who may not realize that a circuit is still powered, and it may prevent automatic re-connection of devices. For that reason, distributed generators must detect islanding and immediately stop producing power; this is referred to as anti-islanding.The common example of islanding is a grid supply line that has solar panels attached to it. In the case of a blackout, the solar panels will continue to deliver power as long as irradiance is sufficient. In this case, the supply line becomes an ""island"" with power surrounded by a ""sea"" of unpowered lines. For this reason, solar inverters that are designed to supply power to the grid are generally required to have some sort of automatic anti-islanding circuitry in them.In intentional islanding, the generator disconnects from the grid, and forces the distributed generator to power the local circuit. This is often used as a power backup system for buildings that normally sell their excess power to the grid.
