1.1 GENERAL

An objective of the inverter is to produce an AC voltage waveform

from a DC supply. The DC supply usually consists of several batteries

connected in series. In typical applications, the input voltage for the inverter is

the same as the DC supply voltage. Also, power is the product of voltage and

current; larger applications require more power from the DC supply thus

making the design in place. The power may be maintained by increasing the

voltage and decreasing the current by the same proportion or decreasing the

voltage and increasing the current in the same proportion. If the DC supply

voltage is to be increased for larger power requirement, the components must

be able to withstand the maximum DC supply voltage.
