DC-DC Converters are essential components in an array of industrial and commercial applications. Such converters are used in all types of products, from small consumer electronics items and mobile-phone chargers, to large industrial motor drives. Amongst these converter designs is the common JVA151500S12-D, a unit that provides a wide range of power and switching solutions.

Functional Capabilities of JVA151500S12-D

The JVA151500S12-D DC-DC Converter is a conversion device with the capabilities to provide a regulated and isolated output voltage of 15 V, regulated over the input voltage range of 9 to 36 Vdc. Operating a current from zero to 1500 mA, the output can be set in voltage or current limit mode, and the converter is approved by the Safety Agency for industrial use.

The JVA151500S12-D is suited for a variety of inductive loader and capacitor reactive loads, and the product comes with built-in features such as under voltage protection, overvoltage protection, overcurrent protection, short-circuit protection, over temperature protection, and electrical isolation.

Application Fields and Working Principle of JVA151500S12-D

The JVA151500S12-D DC-DC Converter is suitable for a broad range of applications, including industrial control and communications systems. It can be found in robotics, machine automation, power supplies, server racks, and HVAC systems, as well as in automotive vehicles, marine and aircraft systems.

The working principle of the JVA151500S12-D is based on the isolated directional Buck converter topology, which provides input-to-output electrical isolation. This electro-magnetic isolation prevents ground loops and prevents surge currents from affecting the input source. The converter uses a high-frequency switching circuit to transfer energy from the input voltage source to the output.

The switching circuit causes the input current and voltage to switch at a high frequency, while a series of diodes and capacitors are applied to filter the current to the output voltage. The filter is formed by the inductor and a FET, so the voltage appears across the output capacitor, which forms the basic Buck converter circuit.

The dc-dc converter provides a controlled output voltage and current, even when the input voltage or current changes. The transformer provides isolation between the input and output, as well as helping to reduce the amount of ripple produced by the switching circuit. Finally, the control circuit provides additional protection against overloads and short-circuit conditions.

Conclusion

The JVA151500S12-D DC-DC converter is a component found in many industrial and consumer applications. This converter is able to provide regulated and isolated outputs and provide current and voltage limit modes, while boasting safety agency approval for industrial use. The working principle of the converter is based on the isolated direct Buck converter topology, and the converter provides a controlled output even when the input voltage or current changes.
