Transformer: Converts the system's 220V or 380V AC voltage to the required AC voltage for delivery to the rectifier circuit via a step-down transformer. The transformer's ratio is determined by the secondary voltage. Transformers: Transformers.
(2) Rectifier and Filtering Circuit: The rectifier circuit converts the alternating voltage Ui into a pulsating direct current voltage. Subsequently, the filtering circuit removes the larger ripple components, outputting a direct current voltage U1 with reduced ripple. Common rectifier and filtering circuits include full-wave rectifier filtering and bridge rectifier filtering, etc.
(3) Filtering Circuit: By filtering out most of the alternating current components from the output voltage of the rectifying circuit, a relatively smooth direct current voltage can be obtained. Each filtering capacitor C satisfies RL-C = (3~5)T/. For a 2 or medium T input alternating current signal cycle, RL is the equivalent load resistance of the rectifying filtering circuit. 36V aviation power supply, 400Hz variable frequency power supply, 115/200V power supply, 27V DC power supply, 400Hz power supply, aviation power supply.
(4) Voltage Regulation Circuit: The function of the voltage regulation circuit is to stabilize the output of direct current voltage, ensuring it remains constant regardless of fluctuations in the alternating current grid voltage or changes in the load.
