Structure and working principle of electronic transformer

Structure:
Control circuit: responsible for controlling the switch of electronic devices to adjust the input voltage and output voltage.
Electronic devices: usually use power semiconductor devices, such as transistors, MOSFET, etc., for voltage regulation and conversion.
Output circuit: transmits the converted voltage to the output end, and also includes filtering and protection circuits.
Working principle:
Input voltage regulation: the control circuit adjusts the input voltage by controlling the working state of the electronic device according to the requirements of the input signal.
Electronic device switch: electronic devices (such as transistors or MOSFET) are periodically turned on and off under the action of control signals. When the electronic device is turned on, the input voltage is transmitted to the output end through the device; when the electronic device is turned off, the output end is disconnected from the input end.
Voltage conversion: by continuously switching, the electronic device can change the effective value and frequency of the input voltage, thereby realizing the regulation and conversion of the output voltage.
Output voltage stabilization: the output voltage is smoothed by the filter circuit, and a protection circuit is added to ensure that the output voltage is stable and not affected by external interference.
