Power electornic lab 4 - Essay Example Two types of power inverters are used according to the applications; voltage source inverters (VSI) and current source inverters (CSI) (Sen, 1997). A voltage source inverter (VSI) converts a DC voltage into an AC voltage, which has a distinctive square wave formation. In the similar manner, a CSI converts the DC into AC with a distinctive square wave formation. In the experiment, a further discussion, calculation and results are discussed to evaluate the functional characteristics of the voltage source inverter. The waveform generated by the voltage source inverter in given below. UPS (Uninterruptible power supply) make utilization of the DC/AC inverter with batteries as the DC source. UPS is mostly utilized as the emergency backup power to maintain the data in computer data systems, maintain undisturbed communication channel, emergency power for homes and offices and selective machines at industries in case of primary power source loss. Ups are also used to correct the condition of under voltage and over voltage in electrical systems. The safety function is used in computer data systems, medical instruments and systems UPS is also referred to reduce harmonic distortion. In this experiment, UPS is tested with different kinds of resistive and inductive loads. UPS is evaluated according to the dissimilar load circumstances in the experiment. In this experiment, both simulation UPS investigation software as well as the real physical investigation in inverter systems is carried to evaluate the performance characteristics of the UPS. The two tests will then be compared to evaluate the operation of the UPS. It is quite clear from the above results that as the load increase the output voltage of the UPS drops. On the other hand, with similar inductive and resistive loads, the voltage drop is more with inductive load that is about 6.64
