Why must a toroidal transformer be used in machinery and equipment? Can't a switching power supply or a square transformer be used?

Before answering the question of why mechanical equipment must use toroidal transformers, let's first solve the question of why mechanical equipment does not use switching power supplies or square transformers. By comparing the performance characteristics and advantages of these three products, we know why we do not consider using switching power supplies or square transformers.

1. Efficiency comparison during work:


We compare products with 50W power. The working efficiency of toroidal transformers can reach 86%-90%, and the working efficiency of square transformers is 80%-84%. If the power is 400W, the working efficiency of toroidal transformers can reach 90%-93%, while the working efficiency of 400W switching power supplies can only reach 78%-85%.


2. Comparison of product service life:


There is not much difference in the service life between toroidal and square transformers. There are many transformers on the market that are more than 20 years old and are still in normal use. But the switching power supply is different. The switching power supply has obvious life attenuation materials, so its service life cannot be compared with that of toroidal transformers. Very few switching power supplies are still in use for more than 10 years. The service life of capacitor electrolysis is generally 2-5 years, which also largely determines the service life of the switching power supply.


3. More flexible customer needs


Why do we talk about more flexible customer needs? Because it is very difficult for many switching power supplies or square transformers to achieve high-power use in multiple scenarios, and it is very difficult to design and produce. This problem can be easily solved on toroidal transformers. For example, for high-power waterproof transformers, it is difficult for switching power supplies or square transformers to meet both waterproof and high-power normal use.


After reading the above 3 points, we can very intuitively see why some machines and equipment or some application scenarios should take toroidal transformers as the first choice. Although toroidal transformers are more expensive than switching power supplies or square transformers, toroidal transformers are more stable in actual use than the other two products and make our customers more assured.
