Title: Switching power source circuit
Inventor: KITANO SABURO
IPC: H02M3/28
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To improve the power conversion efficiency of a switching power source circuit and remarkably reduce the occurrence of noise by utilizing exciting energy accumulated in an inductance as regenerated power after keeping the energy until the next turning-on timing of a main switching element. SOLUTION: The switching period of a transistor Q1 is fixed and the turning-on period (t0 -t1 +>=) of the transistor Q1 and the period (t3 -t4 ) during which an electric current flows to two windings mainly vary depending upon the load condition of the secondary-side output of a transformer T1 . Therefore, the electrostatic energy accumulated in capacitors C1 , C2 , and C4 during the (t3 -t4 ) period is converted into the exciting energy of the primary winding L1 of the transformer T1 during a period (t4 -t5 ) and kept during a period (t5 -t6 ) until the transistor Q1 is turned on next. That is, the duration of each operating period varies depending upon the secondary-side load condition of the transformer T1 and, at the same time, timing adjustment is performed during the (t5 -t6 ) period.

Abstract: PURPOSE:To provide small resistance in the forward direction and large resistance in the backward direction of a check valve by forming a valve piece and valve body integrally of elastic sheet material and shaping the check valve to diverge from the top toward the base in the cross section perpendicular to the direction of flow. CONSTITUTION:A check valve 2 is shaped to be a conical body having a pointed top, and valve pieces 6 are connected to a valve body 4 at the connections 8.
