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 ...

Power-transformer designs minimize weight and cost based on three assumptions: (1) the power source is a sine wave, (2) the frequency is fixed, and (3) the voltage will not exceed a specified maximum.

For the PDF version of this article, click here. In last month's Power Design column, we examined the functional principles of continuous mode (or incomplete energy transfer mode) of a flyback ...

Design engineers are constantly faced with the challenge of specifying a transformer that will meet design specifications as well as cost constraints. The designer who draws up the circuit ...

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 ...

Abstract: Transformers are important components of power systems. This study compares the costs associated with different parts of the transformer. The cost of different components in a power ...

Abstract: This This paper presents transformer design for voltage-controlled oscillators (VCOs). It first presents a quadrature voltage-controlled oscillator (QVCO), which consists of four symmetric ...
