magnitude of input (dc bus) voltage. In ordinary inverters the battery voltage may be just 12 volts and the inverter circuit may be capable of supplying ac voltage of around 10 volts (rms) only. In such cases the inverter output voltage is stepped up using a transformer to meet the load requirement of, say, 230 volts.
