Despite the fact that transformers have been around for nearly a century, there still are seen multiple kinds of transformer failures, which can arise at any point of time. Even if utmost care is taken during the manufacturing, installing, and operation of the transformer, there are possibilities of failures and risks. After all, transformers are electrical devices that can be controlled only to a certain extent.
Almost every electronic equipment that we use today makes use of PCBs; and just like with anything else, failures with PCBs are also possible. Even the best manufactured PCBs can encounter failures, let alone those that are made using cheaper raw materials and amateur practices. But, to be on the safer side, it is always better to have your PCBs manufactured from expert and experienced PCB assembly manufacturers in India, like Miracle Electronics, so that you can get the best possible products that will have a low likeliness of disappointing you. Such expert and specialized manufacturers exercise proper care, and adhere to the exact tolerances set by the designers. Nevertheless, even good quality PCBs can face problems, which must be immediately identified and rectified so as to eliminate any further errors and hinder time and cost wastage. Let’s help you know about the most common PCB failures seen.
Three phase transformers are a constitution of three single phase transformers connected together. And, it becomes obvious that using one single three phase transformer proves to be more efficient and powerful than using three single phase transformers. So, is it just the efficiency that’s making three phase transformers so preferred? There must certainly be something more that’s making these three phase transformers stand out so distinctively from the rest! Let’s help you understand those factors.
Isolation transformers are widely used in the electronic, industrial, and mechanical industries and applications like mining tools, machine tools, safety lighting, indicator power, as well as general circuit control power supply, because of their excellent performance and safety. Now, you’ll say that almost every transformer is high on performance and safety, then what is so special about an isolation transformer that is making it so preferred among so many fields and scopes? Let’s help you know about the major differences between a regular transformer and an isolation transformer that’s making the latter so admired.
With the rising demand of electronics, the manufacturing of PCBs is also increasing at a great speed. In fact, there is a high demand of extreme quick-turn prototype orders so that prototypes can be acquired at the earliest, tested, and then put into full-run production in the shortest possible time. Although it is the manufacturer’s responsibility to fulfill a zero-delay order, as a customer, you could also help in avoiding delays to your PCB order. How? Let’s take a look.
Transformers are basically used to increase or decrease voltages in an electric circuit using the principle of electromagnetic induction, when the supply voltage or line voltage available does not match the input voltage requirements of the device that needs to be operated. There are a variety of different types of transformers used for different applications, each having a different construction and working. But, the basic of every transformer generally remains the same – there are one primary and one secondary coils wound around a core that are responsible for transferring electrical energy by means of a changing magnetic field.
Have you ever pondered over how power is transferred within PCBs to power up our appliances? There are so many tiny components within a single PCB board that designing such a complex power supply to help reach every minute component, requires immense skill, time, and effort. Moreover, with the increase in circuit design density and complexity, the complexity of the design also becomes more magnified. Only a perfect power supply design can overcome this challenge. But, for a perfect design, all the possible problems need to be dealt with. Some such problems that need to be addressed include electromagnetic interference, component selection, reduced current loops, and trace design to handle high currents. In addition, many important parameters like voltage, current, and heat loss need to be considered too. Let’s take a look at the five most important considerations for a PCB power supply design.
Air core transformers, as the name itself suggests, are transformers that have air in their core, unlike other transformers that have some or the other sort of metal around which wires are wound. These are primary transformers that are used in various types of electronic radio and communication devices. The best usage is in small electronic applications like radio transmission.
When you think of a PCB, you’ll imagine a green board with golden coloured dots and lines, and a lot of pins, sockets, and all sorts of tiny electrical components. Did you realize how we mentioned the word “green” in the above sentence? This does not mean that a PCB is always green in colour. You may or may not be surprised to know that a PCB is not always a green coloured board; it could be many other colours like black, white, yellow, red, pink, purple, and blue. Here, there could be two possible questions arising in out mind –
- Why so many colour options for a mere circuit board?
- If there are so many colour options available, why do we always visualize green when thinking of a PCB?
The electronics that we use everyday like fans, lights, air conditioners, geysers, microwave ovens, washing machines, and refrigerators, are all dependent on transformers for perfect functioning. That’s because the power supplied to simple household appliances and sophisticated industrial equipment may be too high or too low. There’s a lot of technology that goes in using low power and high power transmission between circuits; and this is where transformers do the job. The invention of transformers can be considered revolutionary as it changed the way power is transmitted and voltage is regulated. While there are a number of transformer types available, the two main types that are mainly used are step up and step down transformers. Step up transformers are used to increase the voltage of power, while step down transformers are used to reduce the electrical voltage. Let’s take a look at how step down transformers work, and how and where they are used.
