Our second example is more complicated: a switching regulator. A buck-boost converter, presented in picture 5, is a system in which both voltage and current change. In this example, the input voltage range is 10V to 20V, the input current is unknown as it depends on the input voltage as well, and the … See more First, I’ll go through the basics of power dissipation on which all my analysis methods are based. The first rule relating to power is as follows: Input power of the system is always bigger than output power, and it can … See more Often, power dissipation is not constant but varies over time, periodically. In these situations, we still use the same principles to analyze power … See more Power dissipation has a close relationship with the heating of a component, and it is important to calculate in all components we recognize as critical. These components can be … See more The first example is simple but applicable for all electronics engineers: LDO regulator. These regulators can model similar to picture 3.
