There are many people who make use of bi-directional converters but do not know what exactly these converters do. They are suitable for DC power in both directions. These converters are used mostly in the energy storage in the battery bank or as a renewable energy system. Primarily, there are two types: Isolated DC-DC converters and Non-isolated DC-DC converters.

Their Advantages:

Isolated DC-DC converters have a high voltage isolation that runs from several hundred to several thousand depending on the standard-type. The output can be easily configured to be negative, positive or floating on the ground for various type of equipment.

They have a strong interference blocking capability and can produce a strong noise which means providing a load with a cleaner DC source is needed by sensitive loads.

There are certain disadvantages in using these bi-directional converters, as they are large in size, have core-saturation issues and switching losses. Besides, they are somewhat less efficient when compared to the non-isolated directional dc converters. They can also create more leakage losses because of the inductance in the winding. 12v to 24v dc dc converter is a boost DC converter that increases the input voltage.

To put it simply, if you require a floating ground or have safety requirements youshould use isolated converters. Otherwise non-isolated converters are good enough.

What Are Non-Isolated DC-DC Converters?

These types of converters have a DC path between its output and input. The input and output of non-isolated dc dc converter has the same ground. You should consider the 12v to 24v dc dc converter.

Step-up Voltage can be done without use of any transformer. It has the following advantages:

Its circuit is very simple.

There are less witching losses and the numbers of switches are also less

The circuit helps reducing ripple content

Current and peak-to-peak voltages are low

Non-isolated DC-DC can be classified into boost and buck mode.                                                  

Buck Mode:

In this mode only one type of switch is required and it has a high efficiency. But the input current is not continuous and a smoothing filter is normally needed.

Boost Mode:

These types of converters are used for stepping up the output voltage without any transformer. It has a single switch and has a high efficiency and produces continuous input current. Boost converters can step-up the output voltage without a transformer. Due to a single switch, it has a high efficiency. The input current is continuous.

So basically the non-isolated bi-directional dc-dc converters are pretty good and much more sophisticated when compared to the isolated bi-directional dc-dc converters. But you need to keep in mind that the output voltage is very sensitive to the changes in the duty cycles. 12v to 48v dc dc converters are the voltage boost converters that are used primarily in marine, military and industrial systems.
