DC DC Converters

A DC DC converter, or direct current to direct current converter, is a type of power supply that changes a low voltage of direct current to a higher or lower voltage of direct current. In general, the input of the DC DC converter is the higher voltage, and the output is the smaller voltage. It is mainly applicable to the regulated source of the electric motor or the small electronic equipment with low input power supply, and it can be used for various electronic products, like electronic interlocking, uninterruptible power source system, alarm system, musical instrument, LED lighting, etc.

The DC DC converter is composed of three parts: rectifier, filter, and inverter. The rectifier converts the AC to the DC power supply. The filter is used to filter the ripple on the input. The inverter changes the DC to the needed output voltage. In addition, the converter consists of several transistors or electric capacitors that control the conversion process.

The most common application of the DC DC converter is in vehicles. In vehicles, it is used for electric power steering, headlights, radio, air conditioning, motors, etc. It can also be used for battery chargers, computer motherboards, portable electronics, and industrial applications. With the development of modern technology, more uses of DC DC converters have been found. They are widely used in toys, gaming systems, medical equipment, telecommunications, and instrumentation.

VE-B3L-EX-S application field and working principle

The VE-B3L-EX-S DC DC converter is a high-performance bidirectional converter. It is mainly used in the fields of battery energy storage and new energy automobiles for power conversion. It can also be used in distributed energy storage, communication backup power, and other areas to meet the continuous and stable power supply demand.

The VE-B3L-EX-S converter adopts a three-phase common simulation technology, and its main components include a three-phase rectifier bridge, an IGBT power converter, a three-phase synchronous motor, an output filter circuit, and a control unit. The rectifier bridge converts the input AC power into the DC power by using the power switching elements IGBT. The IGBT power converter switches the DC power to output AC power with the input of the pulse control signal. The output filter circuit is used to eliminate the ripple of the output. Finally, the control unit is used to control the entire system and complete the dynamic and static operation switching of the system, including the control realization of the operation switching, parameter tuning, over-current and over-voltage protection, etc.

The VE-B3L-EX-S DC DC converter can provide a high-precision and high-efficiency power conversion. It has a high conversion efficiency of up to 98%, the PWM control technology makes the conversion effect more excellent, and the unique control mode extends the service life of the equipment. In addition, the converter has a favorable price-performance ratio. The three-phase common simulation technology satisfies the demands for energy storage and new energy automobile power conversion.
