DC-DC converters are electrical devices that modulate direct current (DC) power from one potential level to another. Conveniently, such converters are also able to efficiently deliver any required power level. The REC15-2415SZ/H2/M is an efficient and reliable DC-DC converter module designed and distributed by Sunpower. This article provides a detailed examination of the REC15-2415SZ/H2/M’s application field and working principle.

The REC15-2415SZ/H2/M DC-DC converter module is designed for lighting applications. This module allows for the efficient conversion of DC power from 15V to 24V at 15A through a factor correction PFC circuit. This module is also able to continuously convert 15V input into 24V, in order to support applications that require 24V. Apart from this, the REC15-2415SZ/H2/M module is also well suited for LED lighting, industrial automation, control systems, electric vehicles and other similar applications.

The REC15-2415SZ/H2/M module is built with a single-stage PFC circuit. This circuit is composed of an inductor, a rectifier, a capacitor, and a PFC controller, the LMS6002D. The controller is assumed to have a strong adaptive control gain to incorporate different load patterns. It also has an auto-restart and soft-start after a mains surge or phase loss and protection circuits. This feature increases the device’s efficiency even when faced with over-voltages, over-currents, over-temperatures, and other environment variations.

The REC15-2415SZ/H2/M’s power switch is composed of an insulated-gate bipolar transistor (IGBT). This allows for the module to handle power requirements of up to 150W. The IGBT is driven by an ultra-low inductance transformer with a single winding to optimize the circuit’s response to the load. This transformer drives the IGBT in the forward mode, as well as in the reverse mode. As a result, the module is able to efficiently convert power from 5V to 24V.

An on-board RC filter is used to reduce the input noise voltage and transient disturbances. This feature further improves the module’s performance in different load requirements. The REC15-2415SZ/H2/M also features a low cost, easy to assemble and use design. Further, the module has a long lifespan because of its effective protection and cooling functions. Last but not least, the device’s dimensions are ideal for constrained applications.

In conclusion, the REC15-2415SZ/H2/M DC-DC converter module is the ideal choice for a wide variety of power needs. Its single-stage PFC circuit, ultra-low inductance transformer, and IGBT power switch, work together to allow for efficient conversions from 15V to 24V at 15A. What’s more, its RC filter keeps input noise and transient disturbances to a minimum. Not to mention, the REC15-2415SZ/H2/M module is easy to assemble and use, and its dimensions are ideal for constrained applications.
