The Power Quality is the result of continuous improvement, which it can be defined as the absence of any disturbances signal. However, this process of regulation of the electrical sector has not been developed in Venezuela with the same boom as it has been developed in other countries, therefore, the primary source of electricity presents certain difficulties both of internal and external origin, that are evident in the disturbances in terms of its amplitude and frequency values, among others,

... hich are not compatible with the one required by electronic equipment and systems, which it demands power supplies with increasingly smaller tolerances, better ripple levels, and lower distortion levels. For this reason, a Transient Voltage Suppression System (TVSS) is proposed for DEISCA Company electrical installations under the implementation of the multilevel inverter technology, given the number of benefits it provides in every electrical system, in relation to, low harmonic content, low voltage supported by power devices and input currents with low harmonic content, the possibility of operating at low and high switching frequencies, whose switching strategy used to generate the pulses of the multilevel inverter, is the PS-SPWM modulation that allows the conversion and synthesis of a voltage step wave. With the culmination of this research, it was planned to develop a series of conclusions and recommendations adapted to the strengthening of the proposed system, where the criteria of high performance, high reliability, robustness, and simplicity of execution were taken into consideration.
