Publication number: US20220007509A1
Application number: 17/476,019

Abstract:
A voltage regulator module includes a circuit board, a positive input terminal, a negative input terminal, a positive output terminal, a negative output terminal, a switching circuit, a magnetic element and an input capacitor. The switching circuit is disposed on a top surface of the circuit board, and comprises two switches connected in series to form a midpoint, wherein the switching circuit is connected to the positive input terminal. The magnetic element comprises a magnetic core and a conductive structure in the circuit board, wherein the magnetic element and the switching circuit are arranged on the circuit board along a first direction, the conductive structure is connected to the midpoint of the corresponding switching circuit and the positive output terminal. The input capacitor is connected to the positive input terminal and the negative input terminal, and disposed on a bottom surface of the circuit board.

Application number: 17/474,898

Abstract:
An electronically commutated motor driving module for driving a motor includes a voltage detector, an electronically commutated motor driver, a current detector, a voltage converter, and a controller. The voltage detector detects supply voltage to generate a voltage detection signal. The electronically commutated motor driver is supplied by the supply voltage to generate, according to an electronically commutated signal, an operating current for driving the motor. The current detector detects the operating current to generate a current detection signal. The voltage converter converts the supply voltage into an internal voltage. The controller is supplied by the internal voltage and generates the electronically commutated signal according to a plurality of control parameters. When the controller determines that a specific event has happened according to the control parameters, the controller stops generating the electronically commutated signal and then stores the control parameters.

Abstract:
A serial-type diagonal fan assembly having a first fan and at least one second fan is provided. The first fan has a first front fan frame and a first fan wheel. A first hub of the first fan wheel has a radial cross-sectional area increased from a top toward a bottom of the first hub. The second fan has a second front fan frame and a second fan wheel, the second hub of the second fan wheel has an axial cross-sectional area increased from a top to a bottom of the second hub. The first fan and the second fan are arranged in a series. A spoiler is arranged on a second air inlet of the second front fan frame, an outer edge of the spoiler is embedded in a positioning groove of the second front fan frame without protruding from the second front fan frame.
