Abstract: A method for adjusting a release voltage of a power system. The power converter has a power input terminal for receiving a bus voltage, a first resistor coupled between the power input terminal and a sense terminal, a second resistor coupled between the sense terminal and a reference ground, and a bi-directional converter having a first terminal coupled to the power input terminal. The bi-directional converter converts the bus voltage received at the first terminal to a first voltage at a second terminal or converts the first voltage to the release voltage at the first terminal. The method is adjusting the release voltage by changing the ratio of the first resistor to the second resistor.

Abstract: According to one configuration, an inductor device comprises core material and at least a first electrically conductive path. The core material is fabricated from magnetically permeable material. The first electrically conductive path extends axially through the core material from a proximal end of the inductor device to a distal end of the inductor device. The core material is operable to confine first magnetic flux generated from first current flowing through the first electrically conductive path. The inductor device further includes a gap in the core material. The gap (gas or solid material) has a different magnetic permeability than the core material. Inclusion of the gap in the core material provides a way to tune an inductance of the inductor device and increase a magnetic saturation level of the inductor device. The core material includes any number of electrically conductive paths and corresponding gaps.

Abstract: A short protection method for a power converter having an output terminal for providing an output voltage. The power converter works in a hiccup protection mode when a short fault occurs. The hiccup protection mode has a sleep stage and a reset stage, the short protection method detects the output voltage during the hiccup protection mode and sets the time period of the reset stage based on the detected output voltage. The time period of the reset stage increases with the increase of the detected output voltage.
