The flyback design is a switched-mode power supply (SMPS) that’s been used for 70+ years and still going strong. This supply—also called a power converter—has two distinct operating phases, with power ...

When developing TOPSwitch flyback power supplies, transformer design is usually the biggest stumbling block. Flyback transformers are not designed or used like normal transformers. Energy is stored in ...

A new type of DC-DC converter based on Hybrid-switching Method™ and a novel Hybrid Transformer™ enables a high step-down voltage conversion and provides a regulated output voltage of 1V from a 48V ...

The application of electromagnetics has been in practice for more than a century: In 1831, English chemist and physicist Michael Faraday invented the transformer, although he called it an induction ...

In many electrical installations, general-purpose contactors are used to switch the supply voltage to a small dry-type transformer on and off. One common reason this is done is for area lighting ...

The Medium Voltage Transformer/Interrupter Switch Assemblies by Pioneer Dry Type Group provide switching and fault protection for unit substations. Designing and ...

The most common type of power supply today is the switching supply. These units use pulse-width modulation (PWM) to regulate output. Supplies today employ several different PWM circuit configurations.

One of the most dangerous locations in a power distribution system with regard to incident energy is that first panelboard on the secondary of a transformer. With some thought in your design — even if ...
