Claim 9:
10. The front-end switching circuit of claim 9, wherein the front-end switching circuit is configured to control charging input from the DC power source to a first inverter circuit corresponding to a first battery and a second inverter circuit corresponding to a second battery;
wherein when a sum of the voltages of the first battery and the second battery are less than an input voltage of the DC source, the at least one switching device is configured to control the charging input by operating in a first mode; and
when the sum of the voltages of the first battery and the second battery are greater than the input voltage of the DC source, the at least one switching device is configured to control the charging input by operating in a second mode.
