摘要： An embodiment integrated common mode choke comprises a magnetic core, a magnetic plate, a first winding coil and a second winding coil. The magnetic plate is inserted within an inner circumference of the magnetic core. The first winding coil and the second winding coil are wound are wound in the same direction through the magnetic core. The integrated common mode choke is equivalent to a common mode choke and a differential mode choke connected in series. The inductance value of the differential mode choke can be changed by adjusting either the gap between the magnetic plate and the magnetic core or the thickness of the magnetic plate.

摘要： A switching power supply with overvoltage protection includes a soft start circuit, a rectifying circuit, a filter capacitor, a main supply, an auxiliary supply and a monitoring circuit. When the input voltage is higher than the predetermined protection voltage, a first electric control switch is turned off, and the main power circuit of the switching power supply is shut off. At the moment, the actuation and release of the second electric control switch is controlled so as to control the input power supply to intermittently charge the power supply module such that the output voltage downstream of the rectifying circuit inside the power supply is controlled in a safe range. For instance, the second electric control is turned on when the output voltage is lower than a certain value, and is turned off when the output voltage is higher than a certain value. Thus, it is ensured that the bus line voltage inside the power supply is controlled within a safe range, to ensure the safety of the devices inside the power supply; and at the same time to ensure the safety of the inner devices of the switching power supply, such that the auxiliary power supply and the control circuit can work normally.
