Charger: This block rectifies the input AC and charges the batteries. The charger block unit involves an EMI filter,
rectifier, and DC filter. Here is a small explanation of how each sub-component works:
EMI filter: this unit reduces noises and disturbances from the input AC signal.

Rectifier: this unit converts AC current to DC current.

DC filter: The rectifier’s needed output voltage is unidirectional and does not change concerning time. It has an
average or DC value on which AC components of different frequencies are superimposed (mixed). These undesired
AC components mixed in DC are called Ripples. Therefore, filter circuits are necessary for DC Regulation. Thus,
this part task reduces the negative ripple effect and makes the output current much more in DC shape.
Static switch: Static Switches are designed to connect or disconnect the load to or from the supply, respectively,
without the existence of moving parts.

Inverter: DC to AC inverters is designed to change a DC (direct current) power supply to an AC (alternating
current) power supply.
Battery bank: An assemblage of one or more individual batteries used to store energy in electrochemical form is
referred to as a battery bank.
Load: Sensitive and critical loads selected by the user.
