Title: Switching power supply equipment
Inventor: KITANO SABURO
IPC: H02M7/12
Filed: 1997-09-18
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption at light load by preserving exciting energy of an inductance of a loop circuit constituted of a series combination of a parallel circuit of an inductance and a main switching device and a parallel circuit of a capacitor and a diode until the next turn-off of a sub switching device and using it as regenerative power. SOLUTION: When voltage is induced in a secondary winding 5b of a main transformer 5, charging current is caused to flow in a filter capacitor 12 at the secondary side through a diode 17a. At that time, a combined inductance of a parallel combination of a series circuit of a primary winding 5a of the transformer and a choke coil 7, and a choke coil 3, generates resonance current together with a capacitor 4 for resonance. The ON/OFF of transistors Q1 , Q2 is controlled by a PWM control circuit 9. By making a component of voltage higher than √2 times as much as the AC voltage Es be hardly induced in a filter capacitor 8 or making a component of charging voltage caused by the in-flow of regenerative current small, a power factor can be improved. Therefore, whether a switching frequency is fixed or variable, a switching device can be softly turned on at a desired timing.

Filed: 1996-09-26
Abstract: PROBLEM TO BE SOLVED: To eliminate the possibility that outer leads for bridging a second through hole are covered with a covering resin and to prevent the packaging performance of a TAB type semiconductor device from being impaired by a method wherein a projection, which controls the spread of the covering resin, is formed on an insulating film position between a first through hole and the second through hole, which are formed in the side of the rear to the surface, which is formed with a conductive pattern, of a TAB tape. SOLUTION: A projection 6, which controls the spread of a covering resin 5, is formed on an insulating film positioned between first and second through holes 1b and 1c formed in the side of the rear to the surface, which is formed with a conductive pattern, of a TAB tape 3. This projection 6 is extended along one side of the through hole 1c and both ends of the projection 6 are made to bend to the side of the through hole 1b. By forming this projection 6, the resin to spread on the side of the rear of the tape 3 is prevented from progressing by the projection 6 and the possibility is eliminated that the resin intrudes into the through hole 1c.  Thereby, the undesirable spread of the resin is prevented by the projection on the side of the through hole 1b and even if the resin clears this projection, the spread of the resin can be reliably prevented by the other projection on the side of the through hole 1c.
