Working Principle of BD7690FJ-E2

The BD7690FJ-E2 operates according to the principle of PFC. It is designed to provide comprehensive power factor control and management solutions. It works by controlling the current into a boost inductor based on a target input voltage. The regulator works by measuring the output voltage from a reference voltage, which is produced by a voltage divider circuit. The output current is then compared to the target current set by an independent current loop. The controller will then adjust the voltage on the boost inductor accordingly to maintain the correct output power. This ensures that the output is regulated to the desired levels.

The BD7690FJ-E2 is able to accurately control the input of current through a variety of methods. It uses a maximum power point tracker (MPPT) to identify the set of input frequencies and amplitudes which will result in the maximum output power. It also ensures that the current waveform remains sinusoidal and its harmonic content is kept to a minimum. This ensures that the output voltage is maintained at a desired level and minimizes harmonic distortion.

The BD7690FJ-E2 is equipped with an intelligent circuit protection for overload, short circuit and thermal protection. This allows for improved reliability and protects the circuit from a wide range of damages. It also implements a soft-start to help reduce the inrush currents and optimize the start-up time of the power supply.

Conclusion

The BD7690FJ-E2 is a highly efficient and reliable Power Factor Correction (PFC) regulator. It is designed to provide a cost-effective solution for a wide range of applications such as telecommunication equipments, industrial applications and consumer electronics. It accurately controls the input of current, thereby reducing harmonic distortion and improving the output power quality. This PFC solution is also equipped with an intelligent circuit protection to guard against overload, short circuit and thermal damages.
