The effects of arc blast pressures have been theorized for about years, but the direct effect on workers has been less studied. A search of the literature gives no satisfactory quantification for hazard assessment [1] . Most articles to date with any worker focus have measured or predicted noise levels for auditory damage, but there is still no consensus standard or unified method to predict the pressure

The proposed 3DSVPWM method offers advantage of simplicity, amenable

Transformerless inverters (TIs) are widespread in photovoltaic (PV) applications due to their low cost and high efficiency. However, TIs suffer due to leakage current as a consequence of PV parasitic capacitance, and high-frequency common-mode voltage, which has resulted in the emergence of several topological and control scheme modifications.
