DC-DC converters, commonly known as voltage converters, are electronic circuits or electromechanical devices that modify an input voltage into a different output voltage. Generally, these converters are non-isolated devices which are used to convert a voltage from low to high or high to low to satisfy a certain application requirement. The REC15-4815DZ/H3 is a DC-DC converter that offers many advantages that make it suitable for a wide range of applications.
Application Field
Its application field includes telecommunications, industrial automation, instrumentation and measurement applications. In device configuration, output voltage can be adjusted to the pints specified by customers. It is primarily used in isolated point of load converters, where it steps up the voltage to the required point of load voltage.
Working Principle
Working principle of the REC15-4815DZ/H3 DC-DC converter is based on buck topology. Buck topology is one of the most accepted derivatives of switched mode power supplies (SMPS). It is a step-down type of DC-DC converter where transformation ratio is less than one. The output voltage is maintained at a designed level through the Transformation Ratio (TR) of inductor and capacitor. Generally, the gain is determined by the ratio of primary winding turns in a transformer. In case of buck topology, the basic structure includes two capacitors, two diodes, and a transformer.
The whole circuit consists of an energy storage inductor; two power diodes, a switching transistor that provides energy to driving the transformer and a main transformer. The transformer includes a primary and secondary winding. When the switching transistor is in conduction state, current occurs through the primary winding of the transformer, which creates a magnetic flux in the core. This magnetic flux is transferred to the secondary windings through the core and this magnetic flux removes commutation and energy is transferred to the output side. This situation keeps stable until the switch is off.
On the other hand, the working principle of the REC15-4815DZ/H3 DC-DC converter is also based on the use of the switching transistor. The power transistor is driven by a voltage-controlled oscillator, which is modulated by two clock signals that feed the power transistor to control the pulse-width at its output. This pulse-width is regulated to regulate the power output at the secondary side.
The secondary winding consists of two back-to-back, full-bridge rectifiers which produces low-ripple voltage. The current flowing through secondary winding is regulated by the capacitive filter. This filter prevents the current ripple and high-frequency noise from entering the output side. The output voltage is then regulated by a voltage feedback loop.
The use of the REC15-4815DZ/H3 DC-DC converter offers many advantages such as low noise operation, low profile, low voltage regulation tolerance, high power efficiency and wide input and output voltage range. Besides this, it is highly reliable due to its robust construction. It is also suitable for bulk power applications using PFC (Power Factor Compensation) technology.
To sum up, the REC15-4815DZ/H3 DC-DC converters provide an effective and economical solution for a wide range of applications. Its robust construction and high efficiency make it a suitable choice for many device configurations. It also offers many advantages that make it a reliable and efficient device for DC power conversion applications.
