Abstract: A driving circuit for driving a power switch. The driving circuit and the power switch are collaboratively defined as an equivalent circuit. The equivalent circuit includes a first equivalent capacitor corresponding to an input capacitor of the power switch, an equivalent inductor, and a second equivalent capacitor corresponding to a parasitic parameter of at least one driving switch. In the charging procedure or the discharging of the first equivalent capacitor, a change amount of charges in the first equivalent capacitor while a voltage of the input capacitor is changed from a voltage corresponding to no inductor current to a set voltage is larger than or equal to a change amount of charges in the second equivalent capacitor while the voltage of the input capacitor is changed from the voltage corresponding to no inductor current to a steady voltage.

Abstract: A power supply system includes a first converting stage, a second converting stage, and a third converting stage. The first converting stage is configured to generate a first voltage according to a first input voltage. The second converting stage is coupled to the first converting stage in series, and includes a first non-regulated power converter and a second non-regulated power converter. The first non-regulated power converter is configured to generate a second voltage according to the first voltage. The second non-regulated power converter is configured to generate a third voltage according to the second voltage. The second voltage is higher than the third voltage, and a varying range of the second voltage is wider than a varying range of the third voltage. The third converting stage is configured to generate a first output voltage according to the third voltage.

Abstract: A power converter includes a carrier, a first electronic component, a second electronic component, and a connection part. The first electronic component is disposed on the bottom surface of the carrier. The second electronic component is disposed on the top surface of the carrier. A first terminal of the connection part is coupled to the top surface or the bottom surface of the carrier. A second terminal of the connection part is a bonding pad and attached to the first electronic component's surface apart from the carrier. The carrier is disposed at ⅓ to ⅔ of a height of the power-converter. The connection part is fabricated by mechanical support of the first electronic component.
