LPS366-M

AC DC converters are electrical devices or systems designed to convert alternating current (AC) to direct current (DC). The AC/DC conversion process significantly simplifies the task of controlling circuits. Although there are numerous types of AC/DC converters, the LPS366-M is often chosen as it is lightweight, efficient and easy to install. This article will discuss the application field and working principle of the LPS366-M AC/DC converter.

Application field of LPS366-M

The LPS366-M provides low-power ultra-compact system-level power conversion and effective battery charging for various industrial applications. It is ideally suited for telecommunication, machine tool, automotive electronics, uninterruptible power supply systems, and application scenarios that require low-power and high-precision power solutions. The LPS366-M is suitable for applications such as closed-loop positioning control, servo motor control, power frequency inverter control, etc. It can effectively control the frequency, amplitude and speed of AC provided power.

Working Principle of LPS366-M

The LPS366-M AC/DC converter is an integrated circuit based on LC resonant, current-mode control scheme. The system works on a ON/OFF control principle, where a converter-operated switch is turned ON and OFF at a certain frequency rate. The LC resonance tank coupled with the external MOSFET or IGBT produces the output DC voltage. This switching action enables the DC output voltage generated across the load to remain regulated.

The LPS366-M chip, comprising of an analog ramp oscillator, modulator, driver, compensation network and error amplifier, works in tandem to ensure that the output is within the required voltage range and withstands short-term overloads. The chip monitors the output voltage, and as the load increases, the frequency of the switching action is reduced. This helps in controlling the output voltage, ensuring that it stays within the required range, even during varying load conditions.

Conclusion

The LPS366-M AC/DC converter is a powerful device designed for a wide range of applications ranging from telecommunications to power frequency inverters. Its resonant circuit-based operating principle ensures greater control over the output voltage and makes it an ideal choice for low-power industrial applications.
