2. Technical principles of AC to DC conversion
Alternating current (AC) and direct current (DC) are two different forms of current. The direction of AC current changes periodically, while the direction of DC current is constant. The process of converting AC to DC is called "rectification" and is mainly achieved through the following steps:
1.Transformer regulated voltage: First adjust the AC voltage to the required level through a transformer.
2.Rectifier conversion: Converts alternating current to pulsating direct current using diodes or a rectifier bridge.
3.filter smoothing: Smoothes pulsating DC through a capacitor or inductor to reduce fluctuations.
4.Regulated voltage output: Use a voltage stabilizing circuit to ensure stable output voltage.
In recent hot technology discussions,Silicon carbide (SiC) rectifierandGaN (gallium nitride) technologyIt has become the focus because of its high efficiency and low loss characteristics.
