PWM (Pulse Width Modulation) - Inverter high-frequency chopping technique using a means of regulation enabling rapid modification of pulse widths over a single period, thus making it possible to maintain the inverter output within tolerances even for non-linear loads.
Nominal Voltage - The characteristic operating voltage or rated voltage of a battery.
Power source (alternate) - Backup source used in the event of a mains failure. The connection time and the duration of the source depend on the type of source used. (back)
Metal Hydride - An intermetallic compound or alloy in which hydrogen has been absorbed; also, the negative electrode in a nickel-metal hydride battery.
Crest factor (Fc) - Ratio between the peak current value to the rms current value.
Overdischarge - The process of discharging a cell or battery beyond its cutoff voltage and possibly into voltage reversal.
Switching Transients - Rapid voltage peak up to 20,000 volts with a duration of 10mS to 100mS.
