A typical power inverter has some red and black DC terminals on the back end and we find some AC electrical outlets on the front end. This is due to the fact that there are two types of electricity, AC and DC. There is use of an inverter in converting DC or direct current into AC alternating current. In running household electric devices home power inverter provides uninterrupted power. These inverters are available for home in different voltage and load capacities. A DC source is connected to a transformer through the center tap of the primary winding in the basic design of the home inverter. In allowing current to flow back a switch is rapidly switched back and forth to the battery. Power in Inverter Peak power and Typical or Average power An inverter requires Peak or Surge power and Typical or Average (Usual) power. Peak power is the maximum power that an inverter can supply for shorter period of time. A startup peak power is required for some heavy current appliances like motor and refrigerator than they require when running. Typical power is the power that is provided by the inverter on a steady basis. Compared to the peak power this is usually much lower and is even used by power inverter manufacturer. In estimating the battery capacity typical power is useful. Power Rating of Inverter In different Size ratings from 50 VA up to 50000 VA there is availability of inverters. In household applications inverters larger than 11000 VA are seldom used. Maximum peak power or surge power and steady current supply are the first thing you need to consider about the true sine wave inverter system. The surge rating is specified at so many watts that to for so many seconds. This indicates that for a short time the inverter will handle an over load of that many watts. Between inverters and even within the same brand this surge capacity will considerably vary. In covering 99% of appliances usually 3-15 seconds surge rating is enough. Inverters that have lowest surge rating are the high speed electronic switching types. Follow us on Facebook
