SpletThis book provides thorough, up-to-date coverage of all aspects of switched mode power supply technology. Covers the full range of topics associated with the successful design and production of a switched mode power supply. -- Provides a sound, rigorous treatment of the theory, as well as practical applications, to allow the reader to achieve a ... If the SMPS has an AC input, then the first stage is to convert the input to DC. This is called 'rectification'. An SMPS with a DC input does not require this stage. In some power supplies (mostly computer ATX power supplies), the rectifier circuit can be configured as a voltage doubler by the addition of a switch operated either manually or automatically. This feature permits operati… biography actor john mcintireSpletSwitched Mode Power Supplies or SMPS can be classified into two types based on its circuit topology: Non-isolated Converters and Isolated Converters. Non – isolated Converters are a type of SMPS Topology where the switching circuit and output are not isolated i.e. they have a common terminal. biography adverbials
