Can switching power supplies automatically settle charging transactions?
Load balancing is a charging feature for users who operate dual outlets or multiple charging stations in specific locations. Operating a charging station requires your switching power supply (such as an office building) to carry the cumulative sum of the total capacity of these charging stations. Load balancing is distributed proportionally to the available capacity of many active charging stations. In this way, load balancing can provide charging to many electric vehicles in your location within the constraints of your charging station capacity. Your building (switching power supply) can supply 25A. In your building's parking lot, you have a charging station that provides more dual socket 32A. When the car charges, it will charge in proportion to your charging station.
Hub/Satellite is a charging feature for users who want to operate multiple charging stations in one location. To save you time and energy, SMPS can automatically settle charging transactions and also conveniently collect charging station data from a cloud-based management platform: in order to function properly, each charging station needs to send quantities to its system middle. This is where the Hub/Satellite configuration comes in handy. Rather than having each charging station transmit data individually - which would require each station to have its own built-in modem - the hub/satellite enables up to 20 charging stations to communicate via a single modulated signal.
The switching power supply has an associated drive circuit
We can see that the basic circuit configuration of the converter is the series transistor switch TR1, the switching power supply has an associated switching power supply drive circuit, the switching power supply drive makes the output voltage as close as possible to the desired level, the diode D1, the inductor L1. smoothing capacitor C1. The converter has two modes of operation, depending on whether switching transistor TR1 is "on" or "off". When the transistor is biased "ON" (switch closed), diode D1 becomes reverse biased, and the input voltage VIN causes current to flow through the inductor to the connected load at the output, thereby charging capacitor C1. The flow reverses until it reaches a steady state, creating a magnetic field around the inductor L1. This will continue for as long as TR1 is off.
When the control circuit turns transistor TR1 "OFF" (switch is open), the input voltage circuit is disconnected, causing a magnetic field around the inductor which creates a reverse voltage across the inductor. This reverse voltage causes the diode to be forward biased, then the inductor L1 returns its stored energy to the load, acting like a source and sourcing current until a lot of the inductor's energy is returned to the circuit or until the transistor switches again until closed (whichever comes first). At the same time, the capacitor also supplies current to the load discharge. The above is the content about switching power supply drive, I hope it will be helpful and understandable to you.
