For example, it can be used for common fixed-rail 12V system, graphics card VGA card, mobile hard disk, and automotive inverter battery charging, etc. Additionally, due to its low power consumption, it can be used in battery-powered device to maintain power balance.

Working Principle

The basic principle of PQMC3-D5-S24-S is to control the output voltage by increasing or decreasing the duty cycle of a pulse width modulation (PWM) signal. It applies two full bridges, and the frequency of the output voltage is determined by the frequency of the PWM. This frequency depends on the feedback signals, which help to maintain a stable output voltage.The function of the full bridges is to smoothly control the current in both directions, while the internal control circuit generates the PWM signal, varying the duty cycle according to the feedback signals. When the output voltage is lower than the preset value, the duty cycle of the pulse width modulation signal increases, leading to an increase of output voltage. On the other hand, when the output voltage is higher than the preset value, the duty cycle will be decreased, leading to a decrease in the output voltage. In this way, the output voltage can be kept within the range of the preset value.The PQMC3-D5-S24-S also has protection devices for overvoltage, overcurrent and short circuit, so that it can provide safe and reliable power supply for the load.

Conclusion

PQMC3-D5-S24-S is an ideal DC DC converter for various applications. Its low power consumption and wide input voltage range make it suitable for many fields. Moreover, the working principle of the PQMC3-D5-S24-S ensures that the output voltage is accurately regulated and the load is perfectly protected. Therefore, it is highly recommended to use PQMC3-D5-S24-S for different applications.
