DC DC Converters provide mechanisms to step up or step down the voltage and supply the energy needed to run many machines and devices. The VI-24M-EV-F4 DC/DC converter is an example that provides even more functionality in its application field, which is described in this article along with its operating principle.

Application Field

The VI-24M-EV-F4 application field is quite wide, covering commercial, industrial and military applications. This device is typically used to provide an isolation voltage source to a system from both AC and DC sources with a 12 to 24 volt input voltage. It can be used to replace or eliminate signal sensors, or to change the circuit modus operandi. Examples include controlling a servo motor, controlling an electromagnet and controlling an LCD output.

The VI-24M-EV-F4 DC/DC converter also provides pulse-width modulation (PWM) in order to control the load level from a DC source. It includes a built-in regulated voltage generator, timer, current monitoring and protection circuits. This allows it to be used in a variety of applications, including high-voltage and high-current switching and control, LED lighting systems, high power amplifiers, and motion control systems.

Operating Principle

The VI-24M-EV-F4 DC/DC converter has an efficient operating principle. When the power supply is connected, the switching power MOSFETs are automatically turned on and the control circuit is also turned on. When the voltage of the output terminals reaches the set voltage, the MOSFETs are turned off and the control circuit is turned off.

In order to provide a constant voltage, the VI-24M-EV-F4 DC/DC converter uses a pulse-width modulation (PWM) technique. This PWM control method examines the output voltage and adjusts the pulse width of the output signal accordingly. The PWM signal is produced by a timer circuit, and the timer control works in conjunction with a zero current protection circuit. The magnitude of the PWM signal is adjustable and can be set to satisfy the requirements of any application.

The VI-24M-EV-F4 DC/DC converter also includes a zero current protection circuit, which is used to protect the equipment from excessive current load and to prevent damage to the system components. When the input voltage is greater than the setpoint, the converter switches to constant-current control to maintain a stable output voltage and current. This protection circuit also ensures that the current is limited to a safe level when the input voltage exceeds the setpoint. Additionally, the VI-24M-EV-F4 DC/DC converter includes an over-voltage protection circuit, which will shut off the power supply when the output voltage exceeds the setpoint.

Conclusion

The VI-24M-EV-F4 DC/DC converter is a versatile device with an incredibly broad application field, covering commercial, industrial and military applications. Its efficient operating principle uses pulse-width modulation (PWM) to provide a constant voltage and current, and it also includes protection circuits to protect the components from overcurrent and overvoltage. Its combination of features makes it well-suited to high-voltage and high-current applications such as LED lighting systems, high power amplifiers, and motion control systems.
