DC DC Converters

A DC DC Converter is an electrical device that converts an input direct current (DC) voltage into a different output DC voltage. The QBVW033A0B941-HZ Surge Immunity Line Transient is an example of a DC-DC converter. It can be used to provide surge immunity to the line side of the system.

Application Field

The QBVW033A0B941-HZ Surge Immunity Line Transient is suitable for use in a variety of applications such as electronic equipment, household appliances, industrial equipment, office automation, communication systems and automotive applications. It can be used to protect electrical equipment from noise and transients caused by power disturbances, switching operation, lightning strikes and other events, which could damage the components of the system.

Working Principle

The QBVW033A0B941-HZ Surge Immunity Line Transient converter operates by converting the input AC voltage to a low output DC voltage. It also offers high peak current capability (up to 15 picoamperes), high peak output voltage (up to 1500V), and fast response time (within 200 nanoseconds).The converter uses a step-down transformer to reduce the AC voltage. The primary side of the transformer is charged at peak voltage which is higher than the input voltage. The secondary side of the transformer is isolated from the primary side and only sees the voltage on both sides. When the incoming voltage level changes, the secondary side responds and generates a lower output DC voltage. This output voltage is then used to power the equipment.The peak current is determined by the transformer design and the peak voltage is determined by the output capacitance. The peak current is what conducts the surge and the peak voltage is the result of the capacitive coupling.In order to protect the equipment from transients, the converter has an internal clamp circuit which is designed to limit the over-voltage. The clamp circuit will shunt the peak voltage away from the output capacitance and also reset the output voltage to its original level as quickly as possible. The resetting of the output voltage helps to protect the components from damage.The converter also has an over-voltage protection circuit which monitors the output voltage. If the output voltage exceeds the set point, the over voltage protection circuit will immediately shut off the output voltage. This helps to protect the equipment from any potential damage caused by sustained overvoltages.

Conclusion

The QBVW033A0B941-HZ Surge Immunity Line Transient converter is a versatile, low cost, high performance DC-DC converter. It can be used to provide surge protection to electrical equipment and also offers a high peak output voltage, fast response time, and an over voltage protection circuit. The output voltage and peak current are determined by the transformer design and the clamp circuit helps to reset the output voltage.
