V28B36H150BN2

DC-DC converters are commonly used in commercial, industrial and scientific applications where reliable and efficient power conditioning of the input voltage is required. The V28B36H150BN2 is a popular DC-DC converter that is used in a wide variety of applications. This article will discuss the application field and working principle of the V28B36H150BN2.

Application Fields:

The V28B36H150BN2 is a high performance DC-DC converter that is designed to convert high voltage DC input to lower-voltage (for example 24V) output. This converter is suitable for wide range of applications, such as battery chargers, wireless radios, medical systems, instrumentations, industrial automation, telecoms and many more. In a battery charger system, the V28B36H150BN2 is often used to step-down 12V input to the required charging voltage. It can also be used for automotive applications where the 12V battery needs to be converted to 5V or 3.3V output. In addition, some industrial settings that require more than one power rail can also benefit from this DC-DC converter.

Working Principle:

The V28B36H150BN2 follows a two-stage topology which is based on a Voltage Multiplier circuit, commonly known as a Voltage Multiplier Rectifier (VMR). This two-stage topology consists of two stages, the first stage is the VMR along with an interface control circuit, and the second stage is the final output DC-DC converter. The VMR stage takes the input DC power, increases the voltage, and sends it to the second stage. The second stage is a Buck-Boost converter which further regulates the output voltage as desired, and the two stages are isolated by an optocoupler. The output voltage remains constant, regardless of the input voltage condition and line variations.

The V28B36H150BN2 allows the user to adjust the output voltage power via a remote potentiometer. The output voltage range is adjustable between 4.5 to 28V and it provides dynamic response, which ensures both high efficiency and low output ripple. It also features a high-frequency power factor correction circuit and standby current control circuit. The converter is also able to provide protection functions such as overvoltage, under voltage, overload, and short circuit protection.
