Extending the battery run-time becomes the top priority for the system designers. This paper overviews five commonly used DC-DC conversion topologies suitable for battery operated systems: Buck, Boost, non-inverting Buck-Boost, Charge Pump and Flyback converters.
It is worth mentioning that the dc/dc converter must be bidirectional to ensure the power flow of charge and discharge of the batteries [7, 8]. In this sense, the general structure of a BESS connected to the MV grid is shown in Fig. 1. This system is composed of the battery pack, dc/dc stage and dc/ac stage.
This, along with the internal ohmic resistance of the pack and for the LC filter in between the battery and the converter, determines the voltage level to be synthesized at the converter terminals. Such average voltage at the converter terminals will result by applying the maximum possible duty cycle, so around 0.95.

The DC power supply must be capable of supplying up to Connect the panel terminal of the board to the DC source, making sure to maintain the correct polarity. Connect the battery terminal of the board through an ON/OFF switch to maintain the correct polarity. Connect the electronic, resistive, or LED load to the load terminals.
The battery is charging. The average voltage output V0 of the converter (at the battery side) can be expressed as (2) V 0 = V d · ( 2 · D 1 − 1), being D 1 the duty cycle for transistors T1 and T4 (see Fig. 4 ). According to the last expression, for D 1 = 0, V 0 = − V d; for D 1 = 0.5, V 0 = 0; and for D 1 = 1, V 0 = V d.
Under such conditions, it is possible to increase the degree of freedom to control the battery state of charge (SOC). The dc/dc converters also allow using less batteries in series, since the converters can boost the voltages to the grid connection .

Since power generated by solar panels is immediately stored in the battery as DC power and only converted to AC when needed, there are fewer conversions involved. This reduces energy loss and makes them more efficient. Unlike AC-coupled solar batteries, which have a round-trip efficiency of around 90%, DC-coupled batteries have an efficiency of up to …
