DC DC converters are used to convert a direct current (DC) input voltage to a different output voltage level or higher current. VI-B4R-MV DC-DC converters are compact and lightweight, and feature a wide range of output voltage, transient response speed, input voltage, output power and efficiency. This makes them ideal for applications in industrial, medical, automotive and other high-power electronics markets.

The typical VI-B4R-MV application field is high temperature, high-voltage, and high-precision input-output voltage regulation requirements. Common applications include such situations as battery charging, gasoline engine starting, electric heating, electric vehicle power control, and voltage drop compensation.

The VI-B4R-MV DC-DC converter works on the principle of buck-boost conversion. Buck-boost conversion is a process whereby a given input voltage is reduced or increased in order to match the required output voltage. The VI-B4R-MV DC-DC converter consists of two main components: the main power switch and a transformer. The main power switch is the main component responsible for the conversion from AC to DC and vice versa. The transformer is responsible for providing the necessary electrical energy, or “magnetizing current,” to the switch.

The main power switch is a semiconductor device that acts as a switch allowing electricity to flow between two points in one direction and blocking any current in the opposite direction. When the switch is activated, it switches the voltage from the input circuit to the transformer, allowing the transformer to step-up or step-down the voltage and current levels accordingly. When the switch is deactivated, the current in the transformer is blocked and the transformer returns the voltage to its original level.

The transformer steps up or steps down the input voltage as required to provide the desired output voltage. The amount of on-time voltage presented to the input of the transformer varies with the magnitude of the input voltage, so the size of the transformer and its design must be appropriate to the expected voltage and current levels. The transformer also works to ensure a fast, smooth transition between the load and the input voltage.

The VI-B4R-MV DC-DC converter features a built-in automatic protection circuit which monitors the input voltage levels and limits the maximum voltage levels within the system. This ensures maximum protection of downstream electronic components against damage from overvoltage transients.

The VI-B4R-MV DC-DC converter also offers features such as a wide input voltage range, low power loss and low noise operation. The operating temperature range is -40℃ to +85℃, making it suitable for use in extreme environment applications. The VI-B4R-MV DC-DC converter also features a built-in power supply which is housed within a robust metallic case. This helps the unit to dissipate any heat created during operation.

In summary, VI-B4R-MV DC-DC converters are compact and lightweight, and feature a wide range of output voltage, transient response speed, input voltage, output power and efficiency. This makes them ideal for applications in industrial, medical, automotive and other high-power electronics markets. They offer features such as a wide input voltage range, low power loss and low noise operation, and are also suitable for use in extreme environmental applications. The built-in protection circuit ensures maximum protection of downstream electronic components against damage from overvoltage transients.
