DC DC Converters

DC-DC converters are electronic circuit modules used to convert a source of direct current (DC) from one voltage level to another. They are also commonly referred to as DC-to-DC converters. The modified output voltage can be used to power an alternate circuit or to load components such as motors, lamps, or other electrical appliances. DC-DC converters are essential to many applications, allowing regulated voltage strengths suitable for the job, and supplying the appropriate amount of electrical power to circuits consisting of multiple, low-powered components.One such type of DC-DC converter is the VE-223-EX-B1, which is a 125-watt device that is highly efficient, cost-effective, and occupies minimal space. This converter is capable of converting an input voltage of 24 or 48 Volts DC to a selectable output voltage range of 12 or 24 Volts DC, enabling a wide array of applications, such as powering electric vehicles, vending machines, industrial lighting, and other electronic gadgets.

Operating Principle:

The VE-223-EX-B1 achieves voltage conversion by using a switch-mode power supply - a device commonly used to convert electrical power from one voltage to another. Generally, a switch-mode power supply begins with a rectifier, which transforms alternating current to direct current by omitting transient voltages and ensuring that the current passing through the converter is continuous and without reverses in its polarity.The rectified current then passes through an inductor, which helps to maintain the current’s steady flow. From the inductor, the current enters the power switch, which serves as the main component of the switch-mode power supply’s control system. This switch uses a feedback control system, which uses input from the output voltage to regulate the flow of current from the input voltage.The power switch turns the rectified current into a stream of pulses, which flow through a low-pass filter, helping to reduce noise interference and producing a smooth output current. Finally, the output current passes through an isolated, high frequency transformer, which is used to step down or step up the voltage via the transformer’s ratio of primary-to-secondary windings. The output voltage is then fed back to the power switch, which is used to regulate its voltage and maintain the proper output level.

Application:

The VE-223-EX-B1 DC-DC converter can be installed in a variety of different applications due to its ability to efficiently convert an input voltage of 24 or 48 Volts DC to a selectable output voltage range of 12 or 24 Volts DC. Such applications include but are not limited to the following:

• Public address systems
• Emergency lighting systems
• UPS systems
• Industrial process controllers
• Vending machines, and
• Electric vehicle battery storage.

Notably, the VE-223-EX-B1 is also capable of delivering power with a surge rating of up to 50 Watts, making it suitable for battery charging applications. With its high efficiency rating of 92%, minimal space requirement, and cost-effectiveness, the VE-223-EX-B1 is an ideal DC-DC converter for a range of commercial, automotive and industrial applications.
