No plug required for phone charger

To reduce costs, the plug is replaced with a PCB board.
 
RCC (Resonant Continuous Conduction) self-excited power supplies offer several advantages:


High efficiency: RCC self-excited power supplies utilize resonant technology, reducing switching losses and improving overall energy conversion efficiency, thus reducing energy waste.


Low electromagnetic interference: Due to the resonant circuit, RCC self-excited power supplies generate less electromagnetic interference during operation, which helps reduce interference to other electronic devices and improves electromagnetic compatibility.


Stable output: RCC self-excited power supplies can achieve a relatively stable output voltage, which helps protect the charged device and ensures its safe charging.


Simplified circuitry: Compared to some traditional power supply designs, the circuit structure of RCC self-excited power supplies is relatively simple, helping to reduce system costs and improve reliability.


Portable and compact: Due to the resonant technology, RCC self-excited power supplies have a more sophisticated design, allowing for a lighter and more compact product form, making them convenient to carry and use.


Overall, RCC self-excited power supplies, with their improved efficiency, reduced interference, and stable output, provide superior performance for power systems and are gradually becoming an important application in various electronic devices.
