Switching Power Supply: Uses Advantages and Working Principle | Article | MPS
In switching power supply designs the input voltage is rectified and filtered at the input. Then it goes through a chopper, which converts it into a high-frequency pulse train. Before the voltage reaches the output, it''s filtered and rectified once again.
Linear Power Supply vs. Switching Power Supply | Cadence
A DC power supply is also a linear power supply. A switching power supply rapidly switches a power transistor between saturation (full-on) and cutoff (full-off) states, converting an input voltage to a high-frequency alternating current (AC).
Building a DC-DC Power Supply that Works | Analog Devices
Abstract. This article discusses important considerations when designing a DC-DC power supply. Topics include choosing the right DC-DC converter for the application; MOSFET gate capacitance; high switching frequencies and component size; equations and calculations; selecting peripheral components; component placement and trade-offs; …

What Is a Power Supply & How Does It Work?
What Is a Regulated Switching Power Supply? Switching power supplies are more efficient, have higher capacities, and are smaller than their linear counterparts. However, these models generate noise during use, especially when switching power. Switching
Understanding AC/DC Power Supply | Article | MPS
A linear AC/DC power supply tends to have fewer components and simpler circuits, than switching AC/DC power supply. The added noise generated by the transformers forces the addition of large, complex filters, as well as control and regulation circuitry for the converters.
Automatic switching between two power sources
Hi I have a project which gets its power from a car battery or a 12V wall wart. What I''d like to do is have both of these wired in, but when the mains power is present, have the battery no longer supplying. The battery and the mains supply are going to be kept independent, so no charging occurs, and I''d like to make it automatic so the battery …
What is a switching power supply, and how does it work?
