DC-DC converters are electronic circuits that convert direct current (DC) from one voltage level to another, creating an isolated output voltage from an isolated input voltage. These converters are used in a variety of applications, including audio, video, communication, and energy systems. In this article, we will discuss the application field and working principle of the four most common types of DC-DC converters: VE-JNW-CX-S.

VE Converter

The VE converter, also known as the voltage-controlled voltage source converter, is a type of DC-DC converter that operates by taking the input voltage and using it as a control signal for a stabilizing voltage source which, in turn, controls an output voltage. The VE converter is used for many applications such as telecommunications, automotive electronics, welding, and power supplies. To achieve better efficiency, the VE converter typically uses a variable frequency and a low on-time switching scheme.

JNW Converter

The JNW converter, also known as the linear voltage regulator, is a type of DC-DC converter which utilizes feedback control to regulate an output voltage. It takes a preset input voltage and then adjusts the output voltage to maintain a preset ratio of output to input voltage. This converter is used in applications where high accuracy is required and a low noise level is desired. The JNW converter is typically used in audio, video, and communication systems.

CX Converter

The CX converter, also known as the high-frequency switching regulator, is a type of DC-DC converter that provides a highly efficient voltage conversion from input to output. It utilizes switches and capacitors to employ high-frequency pulsed current to drive a low-frequency output voltage. The CX converter is ideal for applications that require a low-load ripple voltage and high efficiency, such as portable electronic devices, voltage regulation, and battery charging. The CX converter typically has an efficient conversion ratio of up to 97%.

S Converter

The S converter, also known as the low-dropout (LDO) regulator, is a type of DC-DC converter that operates with very small input voltage fluctuation and power loss. This type of converter is used in applications such as power conversion, light load detection, and voltage regulation. The S converter provides a high level of accuracy and endures extreme temperatures, making it suitable for applications such as ultra-low voltage regulation, temperature monitoring, and instrumentation.

In summary, DC-DC converters are important components of many electronic systems. The four most common types of DC-DC converters—VE, JNW, CX, and S—all have their own unique application field and working principle. The VE converter is a voltage-controlled voltage source converter, the JNW converter is a linear voltage regulator, the CX converter is a high-frequency switching regulator, and the S converter is a low-dropout regulator. Each of these converters has its own advantages and disadvantages and can be used for a variety of different applications. Understanding the application fields and working principles of these four DC-DC converters can help one make the right choice when selecting the correct converter for a given application.
