dc.description.abstract |
The inverter can be used as a source of ac power in the absence of grid power. The
battery can also be charged by alternative sources of energy if grid power is not
available at all. The unit described works as a batter}' charger when the ac mains
power is available and automatically starts working as an inverter when the mains
power fails. Regulation of the square wave output voltage is achieved by variation
of the pulse width of the waveform. A manual switch is also provided to boost the
voltage at higher loads. Protection is provided against overloading of the inverter as
well as against improper or incomplete connections during charging, thereby
protecting the user as well as the unit. The charging current of the battery as well as
the voltage level of the battery are indicated on the front panel of the unit. The unit
has worked satisfactorily on many types of loads regardless of the high harmonic
content of the square wave output voltage. |
