modern methods of voltage regulation - how to use switching voltage regulators

1-32 — elektor january 1980 modern methods of voltage regulation modern methods or mange regmation how to use switching voltage regulators For optimum performance, it is desirable that good voltage regulators are used in modern electronic systems. Usually, these regulators are of the conventional type based on the series pass transistor. These present few problems either in design or manufacture; however, they are not noted for their efficiency. This has led to an increasing trend to the use of switch-mode power supplies which are far more efficient. In this article we take a look at the advantages and disadvantages of switching regulators from a practical point of view. 1 switching regulator with an efficiency of 75%, the dissipation works out to be 3.3 W, an improvement of 300%! This enables the use of a much smaller heatsink and a transformer of about twq„, thirds the size of that in a conventional system. The other side of the coin Compared with conventional regulators, it...
