DC-DC converters are electrical circuits that take in from a source of direct current, or DC, power and convert it to a different DC voltage. When the source of power is a voltage from an AC outlet, then DC-DC converters are a type of AC-DC power supply. The V72B8M150B is among the most popular of such DC-DC converters, as it provides high efficiency while causing minimal disruption to the environment. In this article, we will discuss the application field and working principle of the V72B8M150B.

Application Field

The V72B8M150B is a medium-power voltage converter usually utilized in industrial, telecom, PLC (programmable logic controller), and consumer electronics. It is especially useful in situations that require a power supply to have a wide input voltage range, high efficiency, and low EMI (electromagnetic interference). The V72B8M150B has been designed to provide stable output voltage under harsh environmental conditions. It can operate at temperatures ranging from -40°C to +85°C, and is still able to deliver up to 160W of power with maximum efficiency of 98%.

The V72B8M150B can provide single and dual output with a range of 1.8-to-7.2 volts. It is short circuit protected, and has an adjustable OVP (overvoltage protection) to ensure safety. Furthermore, it has a built-in soft start feature that prevents inrush current, and also features a wide range of protection functions to ensure reliable over-temperature and load operation.

Working Principle

The V72B8M150B DC-DC converter works on the principle of pulse-width modulation (PWM). In this arrangement, the input voltage is periodically switched on and off, with the on-off ratio controlling the output voltage. The peak input voltage is maintained at a constant level, while the duty cycle of the pulses is adjusted to vary the output voltage.

The principle of PWM switching can be understood using a simple example: Suppose a battery connected to the AC outlet is supplying a voltage of 12V. If a PWM switch is used to control the output voltage of the device, then by varying the on-off ratio of the switch, the output voltage can be regulated. In a 50% duty cycle, it means that the switch is on for 50% of the time and off for the remaining 50%. This will result in an output voltage of 6V.

The advantage of using this principle is that the circuit can regulate the output voltage without having to adjust the current or impedance levels. This reduces the risk of overloading the components, resulting in higher efficiency, and also ensures that the supplied voltage does not exceed the rated limit.

The V72B8M150B was designed to have a self-adjusting protection circuit that adjusts the duty cycle depending on the circuits operating temperature. This ensures that the output voltage remains within the predefined tolerance range, and prevents excessive current from damaging the components. This is especially valuable in applications where peak power consumption is high or fluctuates frequently.

Conclusion

The V72B8M150B is a medium-power voltage converter that has numerous applications in industrial, telecom, and consumer electronics. It uses pulse-width modulation to regulate the output voltage, and features a range of protection functions to ensure reliable operation. It is among the most popular DC-DC converters on the market and delivers high efficiency with minimal environmental disruption.
