The advantages and disadvantages of pulse power supply units

IC step-up/step-down have much more advantages than disadvantages. One of the most important is their very high efficiency, sometimes even more than 90%. This is extremely important in systems based on batteries or batteries. Their relatively small size and light weight is also not without significance. Due to the wide input voltage range (100 to 240 V) allow to apply them in all countries of the world.

No rose without thorns

IC step-up/step-down have several advantages, and among them, among other things, resistance to interference from the network, and short voltage dips. Produced at a lower cost. There is also a build in short circuit protection. But no rose without thorns. There is no perfect electronic devices. Poorly built, or constructed of substandard materials that may cause interference at high frequencies and can lead to unstable operation of the entire system and connected devices. Complex design and the number required for the parts affected the cost of construction of this type of food. The introduction of the relevant integrated circuit in the twenty-first century has allowed, however, to eliminate this problem.

Caution the device is under voltage!

In the systems that feed directly from the network, the main filter capacitor is located behind the rectifier system can keep the voltage because of no load. Avoid contact with him as this may cause electric shock. In years past there were frequent malfunctions of these capacitors caused by the low quality of their production. Frequent consequences was therefore the pouring of the electrolyte, and even the explosion that ended with the motherboard damage and the elements cooperating with it.
