DC DC Converters: V48C8T100BL3 Application Field and Working Principle

DC-DC converters are broadly used to convert an available power source to a higher or lower voltage level. The V48C8T100BL3 is an example of such a DC-DC converter, which is designed to convert a 48V input to an output current of 8A at 100V.

The V48C8T100BL3 is a single-phase isolated DC-DC converter designed for the transportation, HVAC, ATE, and automation industry. It is also compliant with the EN 60950-1 safety standard. Its working frequency is 100kHz and can achieve a wide input voltage range of 36 to 75V with the correct power level. The efficiency of the device is 91.4%, allowing it to operate in wide temperature range of -40 to 85 ℃.

The V48C8T100BL3 features active control such as full protection, EMI noise filtering, unique anti-frequency spread, and a dual-mode output for applications with multiple VMs. It also has a built-in remote monitoring and control network, making it suitable for various applications. Additionally, the device has current trimming, temperature compensation, and voltage adjust functions, making it easy to customize the output power to meet the user’s requirements.

The working principle of the V48C8T100BL3 can be explained using a simple circuit diagram. The device uses a PWM control technique, which works by using the voltage across the output inductor\'s differential to command the duty cycle of the switch in order to regulate the output current. The signal for the PWM control is generated using a High-Low side N-channel MOSFET driver. The N-Channel MOSFET and the Schottky Diodes form a bridge circuit that passes current from input to output. When the switch is closed, the output voltage rises and the output inductor stores the energy. When the switch is open, the stored energy is released to the load. This process continues cyclically, allowing the device to maintain a constant output voltage.

The V48C8T100BL3 is a reliable and high-performance DC-DC converter which is suitable for many different applications. Its high efficiency, wide range of input voltage, and wide operating temperature makes it an ideal choice for use in harsh environments. Additionally, its built-in protection functions makes it a great choice for safety critical applications. Furthermore, its active control and customizable features allow for quick and easy configuration to meet specific needs.
