Title: Switching power converting apparatus
Inventor: MURASATO MICHIHISA
IPC: H02M3/28
Filed: 1994-05-13
Abstract: PURPOSE:To obtain more inexpensive and efficient switching power converting apparatus by providing insulation between input and output. CONSTITUTION:When a switching element Q1 is turned on, current is passed through the switching element Q1, an inductance L1k, the primary winding of a transformer and a capacitor C3. Then a voltage obtained by subtracting the voltage of the capacitor C3 from a supply voltage, is applied to the secondary side of the transformer. The secondary voltage at this time is rectified and smoothed through a diode D1, a reactor L and a capacitor C2, and is output. Subsequently, both of two switching elements Q1, Q2 are turned off, and potential is held by the capacitor C. Further, the diode of the switching element Q2 is put in the forward direction, which allows current to flow to cause zero-voltage switching. When the switching element Q2 is thereafter turned on, almost the same operation is performed in the reverse direction. The above-mentioned operations are repeated. This enables the same operation as with the prior art ZVS methods with a smaller number of switching elements, and obtains a highly efficient switching power converting apparatus.

Title: Periodic signal detector
Inventor: SUGIYAMA HIROYUKI
IPC: H04N5/903
Filed: 1980-09-09
Abstract: PURPOSE: To prevent erroneous detection and to eliminate trouble due to a detection miss by using as a detection output the output of OR between the coincidence signal of a periodic detection signal and a pulse signal having the same frequency, and the pulse signal.  
     CONSTITUTION: A periodic signal fP 3  is outputted from an output terminal 9  through an AND circuit 4 and an OR circuit 8. A counter 2 counts pulses from a clock generator 1 and, when its contents reaches a constant value, permits an AND circuit 3 to generate a pulse. Since the frequency of the pulse is equal to that of the signal fP 3 , inputted to the AND circuit 4, when containing a noise, is not outputted from the output terminal 9. When the signal fP 3  is not detected, it is outputted  from the AND circuit 4 through the OR circuit 8 directly, so trouble due to nondetection is not caused.
