Controller and method for a power converter. For example, the controller includes: a first terminal configured to receive a first voltage; a second terminal connected to a capacitor and biased to a second voltage; a voltage detector configured to receive the second voltage from the second terminal and generate a detection signal based at least in part on the second voltage; a charging controller configured to receive the detection signal and generate a first control signal based at least in part on the detection signal; and a charging current generator configured to receive the first voltage from the first terminal and receive the first control signal from the charging controller; wherein the voltage detector is further configured to: detect that the second voltage has decreased to a first predetermined threshold; and generate the detection signal indicating that the second voltage has decreased to the first predetermined threshold.

Systems and methods for providing power to pulse-width-modulation controllers of power converters during normal operation

Controller and method for a power converter. For example, a controller for a power converter includes: a first drive signal generator configured to generate a first drive signal and output the first drive signal to a first transistor configured to receive an input voltage and related to a primary winding coupled to an auxiliary winding and a secondary winding related to an output voltage; a second drive signal generator configured to generate a second drive signal and output the second drive signal to a second transistor coupled to the first transistor and related to the primary winding; a demagnetization detector configured to generate a demagnetization signal based at least in part on a first voltage related to the auxiliary winding, the demagnetization signal indicating an end of a demagnetization process; and a first controller configured to generate a first control signal.

Switch-mode power converters with control of turning off transistors for zero-voltage switching

System and method for controlling turning on a first transistor and turning off a second transistor. For example, a system for controlling turning on a first transistor and turning off a second transistor includes: a logic signal generator configured to: process information associated with a first voltage related to a second voltage of a first auxiliary winding, the first auxiliary winding being coupled to a primary winding, a secondary winding, and a second auxiliary winding; generate a third voltage based on at least information associated with the first voltage, the third voltage indicating a first voltage difference from a drain terminal to a source terminal of a first transistor related to the primary winding; process information associated with the third voltage and a reference voltage; and change a logic signal from a first logic level to a second logic level.

Disclosed methods provision a host with a pair of proxy resources. A first proxy resource may be configured to forward traffic from an in-band management interface of the host to a link-local interface of a BMC or the like. The second proxy resource is configured to forward traffic received via a link-local interface of the host to a management network interface of a cluster manager. Upon receiving an event subscription message from the cluster manager via the in-band management interface of the host, the event subscription message is forwarded by the first proxy to the link-local interface of the BMC to register a link-local interface of the host as a subscriber for one or more events. Responsive to receiving an event notification from the BMC via the link-local interface of the host, the event notification is automatically forwarded to the management network interface of the cluster manager.

Event subscription for serviceability via bidirectional proxy

The present invention provides a mounting system for a panel, comprising: a clip, a sub-frame, a spacer and a resilient washer, wherein the clip and sub-frame are secured by a screw going through a round hole of the clip, the wing and a hole of the sub-frame. The mounting clip has the following characteristics: reducing the number of clips because clips may be used for both horizontal and vertical mountings of the ceramic panel; the clips are not exposed; the resilient contact between the clips and panels; panels are not vulnerable to come off; the clips can satisfy the separate mounting and removal for panels.

A wind power generation device, comprising a base (), a wind concentrating tower (), a vertical generator (), a vertical spiral turbine (), a turbine air inlet duct (), a trumpet-shaped wind pushing duct () and an umbrella-shaped wind drawing duct (). The wind concentrating tower concentrates the wind, the trumpet-shaped wind pushing duct pushes the wind, and the umbrella-shaped wind drawing duct draws the wind to form an artificial tornado, generate a low air pressure in the center, and generate a great drawing and pushing force to the turbine, thus driving the vertical spiral turbine to drive the vertical generator to generate power. The wind power generation device achieves wind power generation of large installed capacity.
