AC-DC converters are widely used in many industrial applications, from lighting and heating to motor control and solenoid applications. As a result, efficient and reliable converters are required. Enter BP5068-15, a double-converter based on pulse-width modulation (PWM) technology. With a nominal power rating of 15 kW and a single-phase input voltage of 220 to 480 VAC, BP5068-15 is perfect for applications where reliable and robust performance is paramount.

Overview

BP5068-15 is a phase converted, symmetrically modulated PWM dual-converter suitable for power ratings up to 15 kW. The converter consists of one active half-bridge switch per DC-side, which are placed in parallel at the AC-side. This configuration provides redundancy for a safe and reliable operation. The active half-bridge switch and its associated PWM inverse boost rectifier form the core of the converter. The inverse boost rectifier compensates for power dissipation and noise caused by the diode in the passive circuit.

Performance

BP5068-15 provides a voltage regulation that is +/- 1% from no-load to full-load with a 230-Vac input. This makes it ideal for applications where precise voltage regulation is required, such as motors or lighting. Furthermore, it offers an adjustable output voltage range of 10 to 300 VDC (an extended range up to 500 VDC is also available). This provides great flexibility for various applications. It also has an accurate current regulation of better than +/-2% with an input frequency of 50/60 Hz. This allows for safe and precise control of the output.

Safety

Safety is essential in any industrial application. Therefore, BP5068-15 has several safety features to protect and ensure reliability. First, it comes with a 2500 VAC double insulation protection. Second, it has an over-voltage protection to prevent an accidental overvoltage from damaging the equipment. Additionally, it offers an overtemperature protection to avoid overheating of the converter. All these features make the converter versatile and well-suited for a wide range of applications.

How it works

The working principle of BP5068-15 is based on pulse-width modulation (PWM). In this technique, the transistors are switched between the on and off states at high speed. Depending on the duty cycle of the transistors, the output voltage can be adjusted. In the active half-bridge switch, the switching of the transistors is controlled by the PWM algorithm. The algorithm is designed to optimize the efficiency of the converter and provide precise voltage regulation. The advantage of using PWM is that it provides high efficiency, precise regulation, and low switching losses.

Conclusion

BP5068-15 is a highly efficient and reliable converter. Its PWM technology ensures accurate voltage and current regulation with a high degree of flexibility. This makes it suitable for a wide range of applications. It also has a number of safety features that make it even more robust and reliable. Ultimately, BP5068-15 is a great choice for applications where high efficiency, precise regulation, and reliable performance are required.
