Working Principle of 78HT265TC

The 78HT265TC is a DC-DC converter module that uses two switching devices connected in series and connected to pulse-width modulation (PWM) control circuits. It is a kind of switch-mode power supply because the power is controlled through the process of switching two transistors on and off.The working principle of the 78HT265TC is based on an isolated DC-DC Buck converter. The Buck converter acts as an AC-to-DC converter, by taking an input voltage from the power source, rectifying it, and then converting it to a lower DC voltage output.The input voltage is transformed through a transformer in the 78HT265TC. A controller then regulates the flow of current in the primary and secondary windings, as well as the output voltage. An active rectifier is used to turn the AC signal into a DC signal. The output voltage is regulated through a PWM control circuit, which adjusts the duty cycle of the output.The 78HT265TC can operate in both constant voltage (CV) and constant current (CC) modes. The CV mode is suitable for applications where the load current remains the same, while the CC mode is useful for applications with variable load currents.

Conclusion

The 78HT265TC from Sleevepower Technology Co. Ltd. is a high power DC-DC converter module designed for use in a variety of applications. It has features such as high efficiency, support for wide input/output ranges, and full protection functions. The working principle of the 78HT265TC is based on an isolated DC-DC Buck converter, with the input voltage transformed through a transformer and the output voltage regulated through a PWM control circuit. The unit can operate in both constant voltage and constant current modes, making it suitable for a range of applications.
