The versatility of the PQMC3-D48-S12-S allows it to be used in a variety of applications where reliable, efficient power conversion is required.

Design

The PQMC3-D48-S12-S design features a wide input voltage range of 8-48V and output voltage range of 12-15V. It has an efficient design, with a full-load efficiency rating of up to 94%. It also features over-current, over-voltage, and over-temperature protections, making it an ideal choice for applications that require steady and reliable performance. The design also incorporates active PFC (power factor correction), ensuring low ripple and thus keeping the noise level at an optimised level.

Working Principle

The PQMC3-D48-S12-S DC-DC converter utilizes a buck-boost topology to provide reliable power conversion from input to output. In this setup, an inductor is used to store energy and provide a steady current to the output. The current is regulated by switching the input voltage on and off in a process known as pulse width modulation (PWM). As the pulses become wider, more energy is stored in the inductor which is then released as a steady current to the output. This process ensures that the output voltage remains stable and allows for increased efficiency and decreased power losses.

Conclusion

The PQMC3-D48-S12-S DC-DC converter is a reliable, efficient solution for many applications requiring power conversion. Its wide voltage range, efficient design, and active PFC make it an ideal choice for motor control, battery charging, LED lighting systems, and solar power applications. The buck-boost topology used in the PQMC3-D48-S12-S ensures reliable power conversion with low ripple and minimal losses.
