VE-23T-CU Datasheet/PDFDC DC Converters
DC DC converters, also called DC DC power regulators, are useful devices commonly used when the voltage of an appliance must be changed to fit a specific application. The DC DC converter usually changes voltage on either a single system or a single bus. In the single system solution, two energy ports, one input and one output, are used for power conversion, while in the single bus solution, two energy ports and one reference voltage port are present. The reference voltage port is important for controlling the proper voltage being applied to the system.
One particular example of a DC DC converter is the VE-23T-CU. This converter is designed to convert DC input voltages of either 12V or 24V and output adjustable DC voltage between 12V and 19V. With its high efficiency and precision voltage regulation, the VE-23T-CU is a general-purpose converter for applications such as industrial control, automotive, and telecommunications.
Working Principle
The VE-23T-CU is considered a switching DC DC converter, which means it works using a power switch to switch its electrical connections. In this particular DC DC converter, the switch is a high frequency field effect transistor (FET), which can be easily switched on and off, allowing pulses of current to pass through the device.
The process begins when a control component, a high-frequency oscillator built into the circuit, decides when to switch the FET. When the FET is turned on, DC power flows through the converter. During this stage, an inductor in the circuit stores energy from the incoming electrical current. When the FET is turned off, the inductor forces the collected energy to go out of the converter, which in turn produces a voltage drop across a schottky diode.
The schottky diode prevents the voltage from tripping back to the FET, thus providing a regulated output voltage. This output voltage can be adjusted by using a variator, a component which adjusts the duty cycle of the FET switch. The duty cycle of a switching device determines how long the switch is on for compared to the time it\'s off. A higher duty cycle will produce higher output voltages, and a lower duty cycle will produce lower output voltages.
Conclusion
The VE-23T-CU is a great example of a DC DC converter, a useful device for voltage conversion in the wide variety of applications it’s designed to fit. Utilizing a FET switch, an inductor, and a schottky diode, the VE-23T-CU is able to efficiently and precisely convert 12V or 24V input voltages into adjustable DC voltage between 12V and 19V. Through the use of the variator, which adjusts the duty cycle of the FET switch, the output voltage can be tailored to fit the needs of the application in question.
