When initially connecting a battery to an inverter’s capacitive DC input, there is an inrush of current as the input capacitance is charged up to the battery voltage.
But if the inverter switch is open and both batteries are turned on first, then closing the inverter switch handles entire inrush current, while the two batteries split the current equally, cutting individual battery peak inrush in half.
Mainly in any circuit, the input can be either voltage or current source. If the input to the circuit is the dc voltage that is required to be converted into its ac equivalent, then the circuit will be a voltage source inverter. While if the input is provided from a current source then the circuit will be a current source inverter.
The achievable magnitude of ac voltage is limited by the magnitude of input (dc bus) voltage. In ordinary household 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.
Definition: Current Source Inverter is a type of inverter circuit that changes the dc current at its input into equivalent ac current. It is abbreviated as CSI and sometimes called a current fed inverter. Here the input provided to the circuit is a stiff dc current source rather than dc voltage source.
The word ‘inverter’ in the context of power-electronics denotes a class of power conversion (or power conditioning) circuits that operates from a dc voltage source or a dc current source and converts it into ac voltage or current. The ‘inverter’ does reverse of what ac-to-dc ‘converter’ does (refer to ac to dc converters).
