DC DC Converters

A DC to DC converter is a type of circuitry that allows for a conversion of electrical energy from one direct current voltage to another. DC to DC converters are found in a wide range of applications from power supplies, and electronic control systems to batteries, and photovoltaic energy systems. They are popular for their simplicity, efficiency, and cost-effectiveness.

The VE-BW3-EW-F1 is a particular type of DC to DC converter that uses a full bridge topology and has a single input voltage specified from 10-22V. Its output voltage is adjustable from 1.0V to 15V, and it is designed for a continuous output of 3A. It is popularly used in applications such as data-loggers, regulated power supplies, and embedded control systems.

The device features two selectable control modes - continuous mode and pulse-width modulation (PWM) mode. In continuous mode, the converter will regulate its output voltage continuously as the input voltage varies, while in the PWM mode it will regulate its output by turning the output transistor on and off at the specified PWM frequency.

The VE-BW3-EW-F1 uses a full-bridge topology, which consists of two cores: the primary side and secondary side. The relationship between the primary side and secondary side is called a “transformer,” and it enables the conversion process. The transformer is made up of two ferrite cores with two windings each. A voltage applied to the primary side of the transformer will induce a higher voltage on the secondary side, and vice versa. This is due to the inductive relationship between the windings of the transformer.

The transistors used on the primary side act as switches, and can be controlled using control logic. The logic control can be set in either continuous or PWM mode, as previously mentioned. The control logic switches the power transistors on and off, and this in turn creates a high frequency oscillation of the voltage on the secondary side.

The VE-BW3-EW-F1 features a maximum power output of 45W and a efficiency of up to 92%. It is designed to operate in a temperature range of -20°C to +80°C, and has short circuit and overvoltage protections. It also features an input undervoltage protection for safe operation.

The VE-BW3-EW-F1 is an efficient, cost-effective, and reliable DC-DC converter, and is well-suited for use in numerous applications, such as data-loggers, regulated power supplies, and embedded control systems.
