DC-DC converters are devices for supplying different levels of electric current or DC voltages for various applications. Therefore, they are popular in a wide range of industries. Among the various types of converters in use, VI-JNH-CW-S converters are popularly used in many applications. This article seeks to provide an overview of the application field and the working principle of a VI-JNH-CW-S converter.

The VI-JNH-CW-S converter is a bidirectional DC–DC converter that can be used to connect two adjacent power sources, such as a battery and a photovoltaic (PV) source. This converter offers certain advantages over other types of converters, such as flexible power matching, low conduction loss, efficient power conversion, and high reliability. The VI-JNH-CW-S converter has become popular in recent years, especially in the fields of solar energy harvesting, vehicle-to-grid power exchange (V2G), and electric storage facility (ESF).

The converter is capable of operating in both unidirectional and bidirectional power flow modes. In a unidirectional mode, the converter is used to supply power from one source to a load. In a bidirectional mode, the converter is used for exchanging power between two sources. The VI-JNH-CW-S converter can also operate as a step-up or step-down converter, depending on the power requirements of the given application.

The operational principle of a VI-JNH-CW-S converter is quite simple. The converter consists of two switch-mode power supplies (SMPS), one with a higher voltage than the other. The higher voltage supply is connected in series with the lower voltage supply, thus allowing the two power sources to be connected in tandem. The converter then functions as a controllable rectifier that can serve as a unidirectional or bidirectional DC–DC converter, depending on the power flow settings.

The major components of the converter include two SMPS modules, two buck-boost converters, a controller, and a switch array. The SMPS modules are capable of converting AC input voltages to DC output voltages according to the voltage settings of the given application. The buck-boost converters are capable of converting the input voltages to the required output voltages. The controller is responsible for controlling the gate signals of the switches for the operation of the converter. The switch array is used to control the direction of power flow in the converter.

The VI-JNH-CW-S converter is capable of providing a wide range of output voltages and current levels, making it an ideal choice for many applications. Its small size and low power consumption also make it an attractive choice for applications where space and energy efficiency are important. It is also capable of highly efficient power conversion with minimal conduction losses and high reliability. All these features make the converter suitable for use in applications such as solar energy harvesting, V2G, and ESF.
