DC DC Converters

The VE-JWF-EZ-F1 series are high-performance Single-Phase DC/DC converters, with a wide range of input and output voltage levels. These converters are used in a variety of applications, ranging from industrial equipment, computer systems, and automotive applications. They support up to 30 amps of load current, and can provide up to 1000 watts of power.

Each converter module has an integrated full-wave bridge rectifier for converting the input voltage from AC to DC. The converted DC signal is then regulated using a linear or switch-mode regulator, depending on the model. The regulated DC output signal is then converted to the desired output voltage level, using a transformer, inductor, or capacitor-based voltage conversion circuit.

Application Fields

The VE-JWF-EZ-F1 series converters are typically used in power supplies, industrial electronics, medical devices, automotive and charger systems, audio and video equipment, and consumer electronics. Other applications include battery charging circuits, locomotive systems, and household appliances.

The VE-JWF-EZ-F1 series offers a wide range of features, including low ripple and noise levels, high efficiency, low harmonic distortion, high temperature tolerance, and low cost. Additionally, these converters are available in a wide range of form factors, from SIP to DIN-rail mounting. The converters can be used in applications ranging from powering small electronics, to providing high-power output for large aggregates.

Working Principle

The VE-JWF-EZ-F1 converters are high-performance, low-to-medium power DC/DC converters. They utilize a full-wave bridge rectifier for the conversion of AC to DC, and a linear or switch-mode regulator for the regulation of the DC output voltage.

An inverting regulator is used for the linear regulation, and operates by comparing the output voltage to a reference voltage source. If the output voltage is higher than the reference voltage, the regulator reduces the output voltage. Conversely, if the output voltage is lower than the reference voltage, the regulator increases the output voltage.

Switch-mode regulators are used for the regulation of high current outputs. Switch-mode regulators operate by rapidly opening and closing switches on the output of the converter. This process, known as Pulse Width Modulation (PWM), causes the output voltage to fluctuate at a constant frequency. This fluctuation creates a ripple, which is then filtered out before the output voltage is sent to the load. The resulting filtered voltage is the regulated output voltage of the converter.

Conclusion

The VE-JWF-EZ-F1 series DC/DC converters are high-performance, low-to-medium power converters. They offer a wide range of features and performance levels, making them suitable for a wide range of applications. The converters utilize an integrated full-wave bridge rectifier for converting the input voltage from AC to DC, and a linear or switch-mode regulator for the regulation of the output voltage.
