The choice of transformer or uninterruptible power supply transformer can not be simply a “decision either / or”, in particular 10kVA. Both technologies have their place in current scenarios of power protection, but the largest differences important among them: the physical size, efficiency, noise and the amount of input harmonic distortion they produce. Both models produce uninterruptible power source strictly regulated uninterrupted power, but they differ in how it generates the voltage needed by their converters and power amplifiers. transformer based UPS: until the early 1990s, was the conception that the line of uninterruptible power transformer based. Today design is always available, but more often in larger sizes for eight UPS 800 kVA. The most common applications for these large industrial sites. This type of UPS has a robust transformer isolated output voltage that which makes it more suitable for this type of application where there is a risk of electrical noise, spikes, crossing and possibly a high level of short-circuit. The converter generates an alternating voltage of its source DC power is fed into a transformer. The primary function of the transformer, the inverter is to increase the AC voltage required by the load. The processor also protects the converter load disturbances and also a potential separation (a method for isolation of input and output). diverter modern designs use IGBTs (insulated gate bipolar transistors) instead of traditional switch components (such as transistors and thyristors). IGBTs combine the performance of rapid action and high bipolar transistor with the voltage control characteristics of a MOSFET is a versatile, high-frequency form of switching. This has led to stronger, inverters more efficient and reliable. Transformer based UPS is also supplied with an optional dual-entry as a standard that can be easily selected at installation by removing a sheet from the link input terminal. This offer allows two separate fed AC to add additional capacity. An inverter transformer can be installed with the function of double entry, with supplies from the same source, but it is usually a factory option-FIT. Transformer UPS Uninterruptible Power Systems is a new processor Design, usually available from 700VA to 120kVA. The main objective of the introduction of processor units was to reduce overall physical size and weight to an uninterruptible power supply more suitable for small plants and / or computer room , office-type environments where space may be limited. It also produces much less noise and heat than the processor-based cousin, and has much lower levels of input harmonic distortion so that it is compatible with the environments in which electronic devices (computers) may be more sensitive to such distortion. Instead of the transformer, transformer, UPS uses a process directed by the voltage conversion. The first step combines rectifier and a converter to generate a reminder dc power for the inverter. If not controlled, phase bridge rectifier converts the power into a DC voltage. This has gone through a booster circuit midterm, the step voltage 700-800VDC in general, which powered a battery charger and inverter. In the second phase, the power converter and boost converter turns it back into an AC voltage to power the load. Another advantage of this method is that the rectifier operate from three to provide a single phase. It can be configured to install systems to 20kVA. A control system ensures a stable, regulated DC voltage at the diverter provided at any time and the drive can operate independently of the UPS output load fluctuations or power fluctuations or disturbances. The choice of transformer or uninterruptible power transformer in many applications the choice between the two can be unclear. This is where the two ranges overlap in terms of performance, which is the decision more complicated. We must then consider: initial cost, size, operating costs, environmental installation and in particular the amount of the contribution of harmonic distortion they produce. Both versions can be operated in parallel to achieve higher availability and reliability. In the last decade, the gap between these two technologies without power failure has decreased, that manufacturers’ technical and joint research and development efforts, taken to have applied designs. The driving force behind what has cost and size, as well as requests to improve the operational efficiency and reduce harmonic generation. Regarding the online performance of both models offer the same level of performance and are systems VFI (voltage and frequency independent – in accordance with EN / IEC 62040-3). The main differences are its effects on the supply market and operating environment. Transformer UPS are generally recognized as effective and a higher power than a design factor of the equivalent transformer based so that operating costs may be lower. Below 10kVA, which dominates the online design transformer UPS uninterruptible power supply market and has become the standard in data center environments because they offer a compact reduced, greater operational efficiency and reduce noise. But the forces of design-based processor involved in the industry.
