The following is a high-frequency rectifier power supply to share with you the classification of high-frequency switching power supply, there are many circuit structures of switching regulated power supply:

(1) According to the driving mode, there are self-excitation and other excitation.

(2) According to the working mode of DC/DC converter, it is divided into: (1) single-end forward excitation and reverse excitation, push-pull type, half-bridge type, full-bridge type, etc.; (2) Step-down type, step-up type and step-up type, etc.

(3) According to the circuit composition, there are resonant and non-resonant types.

(4) According to the control mode: (1) pulse width modulation (PWM) type; (2) Pulse Frequency Modulation (PFM) formula; (3) Hybrid PWM and PFM.

(5) According to whether the power supply is isolated and the feedback control signal coupling mode is divided, there are isolated, non-isolated, transformer coupling, photoelectric coupling, etc.

The combination of the above methods can form a variety of switching regulated power supplies. Therefore, designers need to effectively combine the characteristics of each method to produce a high-quality switched-voltage regulated power supply that meets the needs.
