DC/DC converters are electronic circuits that convert a direct current (DC) voltage from one level to another. The need for these converters arises from the fact that different electronic devices have different requirements.

Few direct current applications can be imagined without the use of DC/DC converters. While there are many types of converters, one of the most important in terms of its application and working principle is the VE-BTH-EY converter.

The VE-BTH-EY converter is a type of switched mode power supply (SMPS) which utilizes a Buck topology. This is basically a high frequency transformer-less converter. As the name implies, the converter switches between two states: the Buck state and the Boost state. In the Buck state, the output voltage is lower than the input voltage while in the Boost state, the output voltage is higher than the input voltage. The buck-boost converter combines the benefits of the buck and the boost converter to produce high efficiency and small size, while providing benefits such as input voltage regulation, galvanic isolation, energy harvesting, etc.

The VE-BTH-EY converter typically consists of a chopper (switch) and a power factor correction (PFC) control circuit. The chopper switches at high frequencies (typically between 25-200 kHz) to convert the input DC voltage to a desired DC voltage. The PFC control circuit regulates the input voltage, which prevents large surges and drops in voltage levels.

The main working principle of the VE-BTH-EY is based on the Buck-Boost topology. As mentioned, the converter utilizes a high frequency transformer-less architecture which minimizes losses and maximizes the efficiency. The switching of the chopper creates two induced voltages of opposite polarities at the Buck-Boost node. The two voltage sources then form a voltage divider circuit which establishes the output voltage across the load.

In addition to its main application field, the VE-BTH-EY converter can be used in a variety of other scenarios such as input and output regulation, soft start, voltage boosting/drop, etc. For example, the converter can be used for power factor correction (PFC) as well as for input and output voltage or current control. Furthermore, the buck-boost topology employed by the converter is also suitable for energy harvesting applications.

In summary, the VE-BTH-EY converter is an important type of DC/DC converter, particularly in applications which require input and output regulation, high efficiency, and small size. Its main working principle is based on the buck-boost topology, while additional features such as galvanic isolation, power factor correction, etc. make it a valuable choice for a variety of different applications.
