6 FAQs about [How to change the resistance of base station power supply]

How does a switching power supply work?

The switching power supply (SMPS) uses unregulated input DC voltage and switches at a high frequency (10kHz to 1MHz). The duty cycle determines the rectified and smoothed DC output voltage. The SMPS output adjustment also uses a voltage divider, but the switching frequency and duty cycle must be adjusted.

What are the different types of resistors in a power supply?

Almost all resistor choices in power supply designs have different feature priorities and performance requirements, including resistors that can handle the high voltage, high current, and high power, and resistors that require low tolerance.

How does a switching power supply improve efficiency?

As the pressure drop on the load increases, the efficiency will be lower. To improve efficiency, designers often use another power supply topology. The switching power supply (SMPS) uses unregulated input DC voltage and switches at a high frequency (10kHz to 1MHz). The duty cycle determines the rectified and smoothed DC output voltage.

What is the base voltage of a power company?

If the power company delivery voltage is 13.2kV, the base voltage will likely be 13.2kV unless otherwise noted. Voltages are always line-line or phase-phase voltage. Base MVA or Base kVA: A widely used base is 100MVA. But it is possible to select any other base if the operator chooses so. 1MVA=1000kVA.

What is a balancing resistor?

Balancing resistors are used to modulate the load current when multiple power supplies are used. Generally, compared to using a single high-power large power supply, using multiple DC-DC converters in parallel can be cheaper, more energy-efficient, and more compact.

What is a surge limiting resistor?

The surge limiting resistor can limit the amount of surge current that may be caused when the AC-DC power supply is first turned on and the storage capacitor is charged. These resistors are usually very low in resistance and are connected in series with the AC power line.
