摘要： The transformer has a bobbin, a coil assembly and a magnetic core assembly. The bobbin is mounted in the magnetic core assembly and has multiple connecting pins being formed on at least one side of a bottom surface of the bobbin. Each connecting pin has a top surface as a soldering surface that corresponds to a solder pad on a back of a circuit board. At least one fastener is further formed on the bottom surface of the circuit board. Therefore, when the transformer is mounted through the circuit board, the connecting pins are soldered on the back of the circuit board to reduce the total thickness of the combination of the transformer and the circuit board.

摘要： A power converter with synchronous rectifying through the control of a current transformer is disclosed. The basic architecture of the power converter includes a flyback transformer (10), a switch controller (20) and a current transformer (30). The secondary winding of the flyback transformer (10) is connected to the primary winding of the current transformer (30) used to control the switch controller (20). The primary winding of the current transformer (30) is connected to a synchronous rectifying switch (Q7). If a current change occurs on the secondary winding of the flyback transformer (10), the current transformer (30) detects the phase change and enables the switch controller (20) to switch off the synchronous rectifying switch (Q7). The current transformer (30) turns off the synchronous rectifying switch (Q7) anticipatorily in the continuous current output mode to prevent any power loss from crossovers.

摘要： An AC to DC power converter with hold up time function has a charging switch and a mode switch. The charging switch is connected between an output capacitor of a PFC controlling circuit and an energy-storage capacitor. The mode switch is connected between the energy-storage capacitor and an input of the PFC controlling circuit. The charging and mode switches are controlled by a PFC controller. When AC power is normal, the charging switch turns on and mode switch turns off. Meanwhile, the energy-storage capacitor and the output capacitor are connected in parallel to store energy in the energy-storage capacitor. When the AC power source is interrupted, the charging switch turns off and mode switch turns on. Therefore, the energy-storage capacitor is disconnected from the output capacitor. The PFC circuit obtains power from the energy-storage capacitor and continuous to supply an output voltage for a while.

摘要： A power supply having a two-way DC to DC converter has an AC to DC converter and a two-way DC to DC converter. When an AC power is input to the AC to DC converter, the AC to DC converter transforms the AC power to a middle level DC power and the two-way DC to DC converter transforms the middle level DC power to a low level DC power. When the AC power is unavailable and the two-way DC to DC converter obtains an external DC power, the two-way DC to DC converter transforms the external DC power to the middle level DC power. Therefore, if the power supply obtains the external DC power, the power supply can still output the middle level DC power even the AC power is unavailable.
