DC-DC converters are an important component of electronic circuits. They provide a way to convert one voltage source to another in applications requiring low power conversion. The VE-JTM-IW-B1 is a type of DC-DC converter suitable for applications that require high power conversion. This article will explain the application field and working principle of the VE-JTM-IW-B1.

Applications

The VE-JTM-IW-B1 is a robust and efficient DC-DC converter that can be used for a variety of applications. It is particularly suitable for powering medical equipment, industrial machinery, and commercial applications such as lighting. The VE-JTM-IW-B1 has a wide input voltage range (6V to 600V) and can provide output voltages up to 500V. For medical applications, it is designed to be compatible with EMI (electromagnetic interference) standards so it can provide secure power without interference from other equipment.

The VE-JTM-IW-B1 is also suitable for use in hybrid and electric vehicles. Its efficiency and robustness make it an ideal choice for powering electric motors and powering the onboard systems of a vehicle. It is designed to be resistant to environmental conditions and can work in a temperature range of -40°C to + 125°C.

Working Principle

The VE-JTM-IW-B1 uses a unique active-clamped zero-voltage-switched (ZVS) topology. This allows for efficient conversion of input voltage to output voltage with minimum power loss. It relies on a three-stage converter that switches and synchronizes the input voltage to the desired output voltage. The topology is divided into the DC-DC transformer stage, active switch modulator stage, and driver stage.

The DC-DC transformer stage is the main component of the VE-JTM-IW-B1. It converts the input voltage to an intermediate voltage and stores the energy when needed. The transformer has three main parts: the primary windings, secondary windings, and an LC filter. The primary winding is connected to the input voltage source, and the secondary winding is connected to the output. The LC filter is used to reduce noise and ripple that may be present in the input and output voltages.

The active switch modulator regulates the voltage level of the intermediate voltage. It controls the power transfer on the primary winding and provides a stable output voltage regardless of the load. It is made up of four active switches, and each switch opens and closes with a specific pulse width modulation (PWM) signal. The switches are controlled by the driver stage.

The driver stage is the control unit of the converter. It takes inputs from various sensors and uses them to control the timing and duty cycle of the active switches. It monitors the output voltage and adjusts the control signals accordingly. The driver stage can also sense a fault in the circuit or a short circuit and shut off the converter to protect the circuit from damage.

Conclusion

The VE-JTM-IW-B1 is a robust and efficient DC-DC converter. It is suitable for a variety of applications including medical equipment, industrial machinery, automotive, and commercial lighting. The VE-JTM-IW-B1 uses a unique active-clamped zero-voltage-switched topology which is divided into the DC-DC transformer stage, active switch modulator stage, and driver stage. This allows for efficient conversion of input voltage to output voltage with minimum power loss.
