S3HVM2.5 Application Field and Working Principle

S3HVM2.5 rectifier is a single solid state rectifier with a power rating of up to 2.5 amps. It is primarily designed for applications in high voltage and medium power rectification. It works by using power MOSFETs as the main rectification elements, in combination with three additional rectification diodes.

Fields of Application

S3HVM2.5 rectifiers are primarily used in unidirectional power rectification that is used to convert AC power to DC power. They are used in high voltage and medium current applications in industries such as aerospace, medical, and in industrial applications, as well as in high-end consumer electronics. Some other common applications of these rectifiers include: switching power supply systems, uninterruptible power supplies, and power converters.

Working Principle

The S3HVM2.5 rectifier works by connecting three power MOSFETs and three additional secondary rectification diodes. In order to achieve the optimum performance from this rectifier, the power MOSFETs must be connected in a 3-phase rectifier configuration. This 3-phase configuration helps to reduce the voltage drop due to current harmonics, and also improves on the total power efficiency.

When the circuit is powered on, the MOSFETs start to conduct, allowing the current to flow through the diode network. Once the current begins to flow, the power MOSFETs act as rectifiers and the secondary diodes provide protection from any possible additional current passing through the circuit. This ensures that the circuit is safe and effective. As the current passes through the circuit, the excess energy is dissipated through the heatsink, which reduces the overall power consumption.

The S3HVM2.5 rectifier is a reliable and safe solution, and is suitable for a wide range of applications, from power converters to uninterruptible power supplies.
