Title: Switching power source circuit
Inventor: DANJO KENZO
IPC: H02M3/28
Filed: 1989-11-06
Abstract: PURPOSE:To inexpensively balance and enhance an output in a small size by injecting a current based on the induced voltage of a high voltage side feedback winding to a low voltage side smoothing capacitor when the voltages of smoothing capacitors are unbalanced. CONSTITUTION:When smoothing capacitors 3a > 3b are unbalanced, the induced voltage of a current feedback winding lambdaa3 to be added to the inverter transformer 6A of a converter at a high voltage side is injected to the capacitor 3b of low voltage side through a reverse current blocking diode 12a. The energy of the capacitor 3a of high voltage side is transferred to the capacitor 3b of the low voltage side, and the voltages of the capacitors 3a, 3b are balanced. Accordingly, the outputs of secondary windings la2, lb2 of both converters are smoothed by a common smoothing reactor 9, etc., to be supplied to a load to reduce its cost and size. The operating duty of the reactor 9 becomes twice as large as that of prior art, and the output voltage to be supplied to a load becomes twice.

Title: Commutatorless dc motor
Inventor: GOTO MAKOTO
IPC: H02P6/08
Filed: 1990-10-25
Abstract: PURPOSE:To switch current path smoothly and to suppress vibration and noise by generating a ramp signal responsive to a three-phase shaping signal which is further responsive to counter electromotive force, synthesizing a smoothly variable six-phase position signal, and then performing conduction control of a driving transistor group. CONSTITUTION:A first ramp wave generator 3a is provided with a holding signal sa and a first delay signal ma. Since the holding signal sa is 'H', a switch circuit 56a is opened. Consequently, charging current of a capacitor 50a is composed only of the current 11 from a constant current source 51a and thereby a first ramp signal st1 has gentle inclination. A second ramp wave generator 3b receives the holding signal sa and a second delay signal mb. Since the holding signal sa is 'H', a switch circuit 56b opens. Consequently, charging current of a capacitor 50b is composed only of the current 11 from a constant current source 51b and thereby a second ramp signal st2 has a gentle inclination. In such a manner, potential rise during the edge interval of a shaping timing signal m is equalized between low speed rotation and high speed rotation.
