The V48C28H150BS converter is also suitable for use in power converters and power supplies for various military and aerospace applications. It can be used to convert and regulate voltage on a variety of systems, including uninterruptible power supply systems (UPS), aircraft navigation and control systems, fighter mission computers, and communication devices.

The converter also has applications in consumer electronics, such as cell phones, portable gaming consoles, and personal digital assistants. It can also be used in solar power and hybrid electric vehicle applications to convert vehicle power into usable energy.

Working Principle

The V48C28H150BS DC-DC converter is an isolated converter which uses a transformer to isolate the input and output circuits. It operates in a pulse width modulation (PWM) control mode. The power applied to the primary side of the transformer is converted to an AC signal and then rectified and filtered to provide an input voltage signal to the converter IC. The IC contains an oscillator and a control logic which carries out the switching operations according to the programmed parameters.

The IC then generates a logic signal to control the switching of the MOSFETs connected to the secondary side of the transformer. The MOSFETs are switched at frequencies of 50 - 400kHz. The current flowing through the transformer is converted to a DC output voltage which is regulated by the feedback signal from the output stage.

The converter also includes protection features such as overvoltage, overcurrent, and short circuit protection to ensure that the output is safe and reliable. The V48C28H150BS is an efficient and reliable DC-DC converter which is suitable for use in a variety of applications.
