Abstract: A secondary controller applied to a secondary side of a power converter includes a control signal generation circuit and a gate control signal generation circuit. The gate control signal generation circuit generates a gate control signal, and generates an injection signal according to the gate control signal. When a superposition voltage is less than a reference voltage, the control signal generation circuit generates a gate pulse control signal, wherein the gate pulse control signal corresponds to an output voltage of the power converter and the injection signal, the gate control signal generation circuit is further used for generating a gate pulse signal according to the gate pulse control signal, and the gate pulse signal is used for making a primary side of the power converter turned on.

Abstract: Example camera and hub arrangements are presented herein. An example device includes an Ethernet connector configured to provide power and data, a camera port configured to provide power and data to a camera module, and an audio port configured to provide power and data to at least one audio input/output module. The device also includes a processor configured to determine one or more camera parameters for the camera module attached to the camera port, such as a type of a camera module attached to the camera port. The device can change operation mode based on camera parameters and audio parameters associated with connected camera modules and audio modules. Different modules can be connected to the device and located remotely from the device.
