An Overview on Isolated Converters

An Overview on Isolated Converters
With electronic components becoming an integral part of today’s world, power supply converters became more in-demand than ever. As the names suggests, power supply converters are used to step-up, step-down or convert a given voltage level. Using these converters, 220 volts of alternate current can be stepped down to 12 volts DC (common in the case of video game adapters), 12 volts of current can be converted to 3 volts (automotive bulbs feeding from the DC battery), and many other similar applications. Hence, it’s safe to say that supply converters can be used for AC-DC conversion, DC-DC conversion, and the likes.

Today, isolated converters are perhaps the most widely used power supply converters in medical equipment as their output can be positive as well as negative. These power modulators are characterized by the presence of a step-up or down transformer, which may be capable of handling a few to thousands of volts. To help you understand this better, let’s take into consideration the types of isolated converters available in the market.

Flyback Converter

In these converters, a transformer is used to store energy rather than a singular conductor. The flux used in the transformers’ core has irreversible polarity; hence, in order to avoid the subsequent magnetic saturation, the core of the transformer must be large enough for the power level given. Flyback converters are used in applications involving low power.

Forward Converter

The transformer used in these converters transfers the power between the input and the output in a singular step. These converters can step-up, step-down, or even offer a combination of the two. For achieving multiple outputs, all you need to do is tweak the turns on the secondary winding of the transformer. One of the most profound applications of forward converters is car audio amplifiers wherein low voltage from the DC battery is stepped up in order to obtain higher output for the amplifiers.

No matter whether you are looking to buy suitable convertors for AC-DC, AC-AC, or DC-DC conversion, the web promises to be the ideal marketplace for buying such converters. Thanks to the development of the World Wide Web, buying pretty much everything under the sun has become a whole lot easier and electronic components stand as no exception. However, before placing your order, always check the quality of the components being sold by the chosen online seller by reviewing the customer reviews they have received.
