Abstract: An active bridge rectifying control apparatus includes a bridge rectifying unit and a rectifying control module. The rectifying control module includes a phase control unit, a low-side drive unit, and a self-drive unit. The phase control unit provides a live line signal and a ground line signal according to a positive half cycle and a negative half cycle of an AC power source. The low-side drive unit provides a low-side control signal according to the live line signal and the ground line signal. The self-drive unit establishes a drive voltage according to the positive half cycle and the negative half cycle of the AC power source, and provides a high-side control signal according to the low-side control signal. The bridge rectifying unit rectifies the AC power source into a DC power source according to the low-side control signal, the high-side control signal, and the drive voltage.

Abstract: A hybrid power conversion circuit includes a high-side switch, a low-side switch, a transformer, a resonance tank, a first switch, a second switch, a first synchronous rectification switch, a second synchronous rectification switch, and a third switch. The resonance tank has an external inductor, an external capacitance, and an internal inductor. The first switch is connected to the external inductor. The second switch and a first capacitance form a series-connected path, and is connected to the external capacitance. The first and second synchronous rectification switches are respectively coupled to a first winding and a second winding. The third switch is connected to the second synchronous rectification switch. When an output voltage is less than a voltage interval, the hybrid power conversion circuit operates in a hybrid flyback conversion mode, and otherwise the hybrid power conversion circuit operates in a resonance conversion mode.

Abstract: A connector is disclosed and includes a housing base, a conductive terminal, a signal terminal and a protrusion. A sleeve of an electronic device end sleeves on the housing base through an opening end along a first direction and slides a first displacement distance, plural contact pins of the electronic device end slide into the accommodation space through the opening end, and a conductive contact pin of the electronic device end is interfered with the conductive terminal to form an electrical connection. The protrusion is elastically connected to the housing base and penetrates through the housing base. When the sleeve passes through the opening end and slides a second displacement distance greater than the first displacement distance, the protrusion is interfered with the sleeve and drives the signal terminal, so that the signal terminal pushes against a signal contact pin of the electronic device end to form an electrical connection.

Abstract: The present disclosure provides a DC motor driving system including a DC motor, a power supply device, a switch circuit, and a microprocessor. The power supply device provides an input electrical energy. The switch circuit receives the input electrical energy and outputs a motor electrical energy, which includes a motor power and a motor voltage, to the DC motor. The DC motor driving system switchably works in a constant-voltage mode, a first variable-voltage mode, or a second variable-voltage mode. In the constant-voltage mode, the input electrical energy remains unchanged. In the first variable-voltage mode, the microprocessor controls the power supply device to adjust the input electrical energy for increasing the motor voltage and the motor power. In the second variable-voltage mode, the microprocessor controls the power supply device to adjust the input electrical energy for decreasing the motor voltage and keeping the motor power unchanged.

Abstract: A connector is disclosed and includes a main body, a sleeving component, a conductive terminal and a signal terminal. The main body has an opening end and a sleeved end opposite to each other. An electronic device end is matched with the connector through the opening end. The sleeving component is slidably disposed on the sleeved end, and includes a conductive contact portion and a signal contact portion arranged in parallel. The conductive terminal is fixed to the main body for connecting with the conductive contact portion. The signal terminal is fixed to the main body for connecting with the signal contact portion. When the connector is detached from the electronic device end, the sleeving component is displaced relative to the main body, the signal contact portion is separated from the signal terminal, and the conductive terminal end and the conductive contact portion are maintained in an electrical connection.
