Abstract

The invention provides a surge protection circuit with an integrated monitoring function. The surge protection circuit comprises an input end, a rectifier circuit and a first capacitor, wherein the input end is at least provided with a first connection and a second connection, and the input end is configured to be coupled to an alternating current power supply and a downstream assembly relative tothe surge protection circuit; the rectifier circuit is coupled to the input end, and the rectifier circuit is provided with a first output and a second output; the first capacitor is coupled to a first output of the rectifier circuit and a second output of the rectifier circuit, and is configured to receive a surge at the input through the rectifier circuit to protect the device. According to theinvention, at least one defect in the prior art can be overcome.

Description

technical field [0001] At least one aspect of the invention generally relates to surge protection for electronic devices. Background technique [0002] It is known in the art to use power supply devices such as Uninterruptible Power Supplies (UPS) to provide regulated, uninterruptible power to sensitive and / or critical loads, such as computer systems and other data processing systems. Whenever electronic equipment such as a UPS is connected to the grid, the equipment can be subject to voltage transients (surges) due to upstream component failures, coupling of large transformers to electric motors, and lightning strikes. Contents of the invention [0003] According to one aspect, the present invention provides a power supply device, which includes an input terminal, a converter circuit, a load output terminal, a rectifier circuit and a first capacitor; the input terminal has at least a first connection and a second connection, the input terminal is configured to be coupled...
