Working Principle

The working principle of the VHK100W-Q48-S12-DIN is based on a two-stage conversion process. First, the AC input is rectified and converted to DC, then the DC output is generated by a constant frequency, pulse-width modulated (CPWM) buck-type switching converter. The output voltage is regulated by the control loop, which converts an error signal into a signal to adjust the duty ratio of the switching converter. This duty ratio determines the output voltage level.

The switch-mode power supply circuitry consists of a full-bridge rectifier, an input filter, a power stage, a control stage, a feedback stage, a transformer, and a rectifier. The full-bridge rectifier is the first stage in the conversion process. It converts the AC input to DC, which is then filtered and sent to the power stage. The power stage is where the PWM switching devices control the output by regulating the amount of power that is sent to the transformer.

The control stage consists of a control loop that converts an error signal into a signal to adjust the duty ratio of the switching converter to regulate the output voltage. The feedback stage is responsible for comparing the output voltage to the set voltage and generating the error signal. The transformer isolates the power stage from the control stage, and the rectifier is used to convert the AC output back to DC.

Conclusion

The VHK100W-Q48-S12-DIN is a switch-mode power supply that is a highly versatile and reliable solution for a wide range of applications. It can be used in automotive, industrial, telecommunications, consumer, and medical applications. The two-stage conversion process of the unit is based on a full-bridge rectifier, an input filter, a power stage, a control stage, a feedback stage, a transformer, and a rectifier. This makes it a reliable and efficient option that provides a dependable and consistent source of power.
