Common Power Supply Topologies
The three basic topologies used in switching power supplies are buck
The three basic topologies used in switching power supplies are buck, also known as forward, boost and buckboost, also known as Flyback. All three topologies use the same three elements, transistor, inductor and diode but they are arranged in different manners. The essential difference between the three topologies is that the buck has an output voltage lower than its input, the boost has an output voltage higher than its input and the flyback can have an output voltage either higher or lower than its input but inversed in polarity.

In a typical car today, electronic systems are critical to the smooth and safe operation of the vehicle. Even before the engine starts, electronics have already unlocked the car. Once you start the engine and step on the accelerator, sensors assist in getting out of your parking space, engine control units (ECUs) tune the engine performance, monitor the pressure of the tyres and safety systems are powered up in standby mode. As you pull away, adjust the air conditioning, ensure your phone is connected to the entertainment system, set your destination on the satellite navigation system and initiate your favourite music, yet more electronic systems are brought to life.
