LM317T Voltage Regulator with Pass Transistor

Deals with the operation of the fuel pressure limiter or regulator. Also explains safety issues in dealing with newer piezoelectric Diesel injection systems. Common rail Diesel fuel injection is now the state of the art in engine injection. The Bosch Piezoelectric (crystal) injector operates using a crystal stack, usually Quartz, that changes size when energized. The piezoelectric effect states that when a crystal such a Quarts is squeezed an electric current is generated. By the same token, when electricity is applied to the crystal is changes shape. This minute change in crystal size is used to trigger a small fuel chamber on and off. In turn, this chamber creates a pressure differential at the top of the injector which make it open and close. See further information here. Presented using advanced software CG animation technology to help you understand. Part of our Diesel and electronic series shown here on this channel. Enjoy...

Switching Voltage Regulator. Principle of OperationSwitching regulator is a voltage regulator which operates in the switching mode. Most of the time a regulating element is either in a cutoff state at maximum resistance, or saturation state at minimum resistance, hence it can be viewed as a switch. In a switching regulator, the current from an unstabilized external source is fed to a storing element in short pulses, a storing element is usually an inductor; energy is accumulated in the process, and then it is released to a load in the form of electrical power but with a different voltage. The regulation is achieved through the control of pulses and intervals between them, ie pulse-width modulation. Switching regulators have higher efficiency than linear regulators. According to the relation between input and output voltages, switching regulators are divided into: DC-DC converters, DC-AC converters, AC-AC converters, DC-AC converters. According to the switch type: field-effect transistor, thyristor, bipolar transistor. And as a storage element, an inductor, a battery or a capacitor is used. Below there is an example of how a switching regulator can be used as a DC-AC converter, with an inductor as a storage element. In this converter, the switch is placed after the inductor. When the switch is closed, the source current flows through the inductor L increasing the current and accumulating the power. When the switch is open, the source current flows through the inductor L ...
