In modern electronic devices, switch mode power supplies have been widely used as an efficient and stable power supply method. Half bridge and full bridge switching power supplies are two common topology structures of switching power supplies, which have certain differences in working principles, performance characteristics, and application scenarios.Operational PrincipleThe half bridge switching power supply only has two switching tubes, which alternately conduct and cut off, and transfer energy through a transformer. The full bridge switching power supply has four switching tubes, forming two bridge arms. The diagonal switching tubes conduct and cut off simultaneously, and energy is also transmitted through a transformer.Performance characteristics1. Output power: The full bridge switching power supply can provide higher output power, suitable for high-power load applications.2. Efficiency: Half bridge switching power supplies have higher efficiency in a higher power range, while fu...

The core working principle of a DC power supply is to convert fluctuating AC power into stable DC power. The key to this transformation lies in the application of rectifiers. A rectifier, like a sophisticated conductor, accurately captures the positive and negative half cycles of an AC signal and cleverly converts the negative or positive half cycles into a single direction of current. After the initial treatment of the rectifier, the direct current has begun to show signs, but there are still some unstable factors mixed in - ripples and fluctuations.To eliminate these unstable factors and ensure the stability of the output voltage, a filtering circuit is usually connected after the rectifier. The filtering circuit is like a meticulous craftsman, carefully polishing the output voltage to make it smoother and more stable. Under the fine tuning of the filtering circuit, the ripple and fluctuation in the output voltage are greatly reduced, providing reliable guarantees for subsequent cir...
