SWITCHING MODE POWER SUPPLY AND CONTROLLING METHOD THEREOF - A simplified explanation of the abstract

This abstract first appeared for US patent application 18206428 titled 'SWITCHING MODE POWER SUPPLY AND CONTROLLING METHOD THEREOF

Simplified Explanation

The patent application describes a switching mode power supply that converts input alternating current (AC) voltage into a direct current (DC) voltage.

• The power input unit receives the input AC voltage.
• The rectification unit converts the input AC voltage into a rectified form.
• The condenser smooths the rectified voltage.
• The current detection unit detects any surge current flowing in the condenser.
• The converter, which includes switching elements, generates the DC voltage based on the voltage across the condenser and the on/off duty ratios of the switching elements.
• The switching elements are turned off when the current detection unit detects a surge current.

Original Abstract Submitted

A switching mode power supply including: a power input unit configured to receive an input alternating current (AC) voltage; a rectification unit configured to rectify the input AC voltage; a condenser configured to smooth the rectified input AC voltage; a current detection unit configured to detect a surge current flowing in the condenser; and a converter including switching elements, the converter being outputting a direct current (DC) voltage based on a voltage applied to first and second ends of the condenser and on/off duty ratios of the switching elements. The switching elements are configured to be turned off based on the surge current being detected by the current detection unit.
