Introduction

DC DC converters are used to convert the electrical energy of a DC power source, such as a battery, to the required voltage and/or current level for a particular application. The two most common types of DC DC converters are isolated and non-isolated. Isolated DC DC converters are used to provide galvanic isolation between the source and the load, while non-isolated converters are used to connect a source directly to the load. There are various topologies for DC DC converters, including buck converters, boost converters, and buck-boost converters.The VE-B4B-IX-F4 is a unique DC-DC converter that combines the characteristics of both an isolated and a non-isolated converter. It is a multi-level switching converter that is designed to provide voltage isolation along with a wide range of output voltage levels and high efficiency.

Application Field

The VE-B4B-IX-F4 is ideal for use in industrial, medical, and automotive applications, as well as in military and aerospace applications. In the industrial market, the VE-B4B-IX-F4 can be used in a wide variety of applications, from powering sensors for machinery to supplying electrical power for industrial systems. In the medical sector, the converter can be used to provide a reliable power supply for medical devices such as infusion pumps and respiratory systems. In the automotive sector, the VE-B4B-IX-F4 is often used to power dashboard and entertainment systems. Other potential uses for the converter include power supplies for professional audio equipment, radios, avionics systems, mobile radio transmitters, and test instruments.

Working Principle

The VE-B4B-IX-F4 uses a multi-level buck-boost switching converter with an advanced synchronous rectification circuit to achieve both galvanic isolation and a wide voltage range. It employs multiple levels of switches or MOSFETs, with each switch operating at a lower voltage level than the previous switch. This allows for greater efficiency than a single-level converter, as the output voltage is regulated at a lower voltage level. The converter can be set to operate in either buck or boost mode based on the input and output voltage levels.

The converter can also be configured for either CCM or DCM (continuous-conduction mode or discontinuous-conduction mode) operation. In CCM mode, the inductor current is always in the same direction, while in DCM mode, the direction of the current is reversed periodically. This allows the converter to be operated with lower input voltages than those required for CCM operation. The output voltage of the VE-B4B-IX-F4 can be set from 1 to 50 volts, and the input voltage can range from 2.5 to 200 volts. The converter offers high efficiency over the entire operating range.

Conclusion

The VE-B4B-IX-F4 is an advanced DC-DC converter that combines the characteristics of both an isolated and a non-isolated converter. It is ideal for use in a variety of applications and offers high efficiency and a wide range of output voltage levels. The multi-level buck-boost switching circuitry allows the converter to be operated in either buck or boost mode while offering galvanic isolation. The operating range of input and output voltages, as well as the choice of either CCM or DCM operation, adds to the versatility of the VE-B4B-IX-F4 and make it a great choice for many applications.
