For battery chargers, this trade-off is usually optimized to minimize the size and cost of the components while keeping the system power dissipation below the thermal limit. Thus switching frequency is increased primarily to improve the power density (size) of the charger until a thermal limit is reached.
This is a charging method where batteries are charged with a constant current from beginning to end. A standard switching power supply is a constant voltage power supply, so it monitors fluctuations in output voltages, inputs the results in the control circuit, and executes constant voltage controlling also known as feedback controlling.

In this switching circuit, the source of power supply to a load circuit is changed between the battery and DC power. The main components that play important roles in the functioning of this circuit are the relay, switching transistors, and zener diode. In this circuit,three relays are used.
The charger circuit can be divided into three basic blocks. The first is the voltage loop control and state control logic which executes the control algorithm while providing temperature compensation. The second is the switchmode controller which regulates the current to the battery as commanded by the voltage loop control and state control logic.
