The DC-DC converters are one of the most commonly used and reliable components for power supply systems. The QLS12ZG-NT series converters are the most advanced and mature product in the global market for DC-DC conversions. It integrates switching, drive, modulation, and control functions as well as protection and monitoring functions into a single integrated circuit. It is widely used in various industries such as industrial, automotive, military, and medical.

Application Field

QLS12ZG-NT series converters are widely used in various fields. In industrial areas, they are typically used as a DC-DC converter to provide the regulated output voltage from a battery or other DC power sources such as solar cells or fuel cells. When the power source drops, the controller boosts the voltage output to maintain the regulated power output. This helps to increase the efficiency and sophistication of the system, while also providing safety and reliability. In addition, they are also used to provide a clean and regulated supply voltage to sensitive electronics such as communications, navigation, and automation systems.

The QLS12ZG-NT series converters are also widely used in automotive applications. It is commonly employed in vehicle electric systems to provide clean and reliable power to microcontrollers, display screens, sensors, actuators, and other electronic components. With its excellent temperature operating range and high efficiency, it is also used to power charging systems, electric power steering systems, and air conditioning systems.

In military and medical applications, the QLS12ZG-NT series converters are often used as an internal power supply for equipment such as torpedoes, missiles and warheads. It is also used to power medical instrumentation and other sensitive electronics used for monitoring and control.

Working Principle

The QLS12ZG-NT series converters utilize a switching topology for power conversion. This topology is based on an integrated circuit that contains two or more transistors connected in series and capable of switching operation. In its simplest form, the transistors are alternately turned on and off at a frequency determined by the user, causing current to alternate between the two of them. This results in a ripple of voltage and current, with the voltage alternately increasing and decreasing at the modulated frequency. This ripple of voltage and current is then filtered to produce a regulated DC voltage.

Additionally, these converters also have various protection and monitoring functions built into the integrated circuit. This includes over voltage protection, under voltage protection, short circuit protection, temperature detection and fault detection. This helps to enhance the safety and reliability of the power system.

In conclusion, the QLS12ZG-NT series converters are widely used in various industries and fields as a reliable and efficient power conversion solution. They are capable of providing a clean and regulated output voltage and incorporate various safety and monitoring functions for enhanced reliability.
