DC-DC converters are devices used in a wide variety of applications to convert one DC voltage level to another. One type of DC-DC converter is the VE-21V-MV converter. This device is used to convert a single-phase input voltage of 21 volts (V) to multiple output voltages of 5.2 volts (V) or less.

The VE-21V-MV is a high efficiency, switch-mode converter that uses a full-bridge buck-boost topology. It has a wide input voltage range of 15 to 27 volts (V), and an output voltage range of 0.75 to 5.2 volts (V).

The device utilizes a power MOSFET (metal-oxide semiconductor field-effect transistor) bridge circuit and diodes to control voltage in two directions. The power MOSFETs are used as switches to control the flow of current in either the bucking or boosting direction, depending on the direction the switch is set. The diodes reduce the voltage by providing a path for current to bypass the switch, or allow the voltage to increase when the switch is not set. When the power MOSFETs are set in the bucking direction, they act as a rectifier and regulate the output voltage.

The VE-21V-MV converter has various features that make it beneficial for its applications. It has adjustable current and overvoltage protection, noise reduction, zero voltage switching, and an ultra low operating temperature (down to -40°C). It is also certified for safety and compliance by UL, CSA, and IEC standards, making it suitable for many applications.

The VE-21V-MV converter is primarily used in cost-effective, space-efficient industrial applications, such as specialty oil and gas pumps and turbines, automated manufacturing and packaging machines, robotics, mechanical and electrical control systems, power tools, pumps, and blowers. It is also used in the automotive industry for electric and hybrid vehicles, and in the energy industry in solar cell and wind turbine systems.

The working principle of the VE-21V-MV converter is to use the power MOSFET bridge circuit to switch between the bucking and boosting mode. This switching is done by sensing the input voltage and either increasing or decreasing the voltage based on the output needs. The signal for the switching is given to the power MOSFETs by the control circuit. In the bucking mode, the voltage level is proportional to the current in the bridge. In the boosting mode, the voltage is proportional to the voltage of the input.

The VE-21V-MV converter is a highly efficient and reliable device that can be used in a variety of applications. Its features ensure that it meets the stringent requirements of industrial and automotive applications. With its adjustable current and overvoltage protection, noise reduction, and zero voltage switching capabilities, it is an optimal choice for those looking for a stable and reliable power solution.
