Filed: 1992-11-13
Abstract: PURPOSE:To make it possible to adjust power supplied to a load without fluctuating a frequency, and lighten a discharge lamp, as a load, stably in a deep dimming state. CONSTITUTION:A set of serially connected switching elements S1 and S2 or S3 and S4 is connected to a DC power supply. An inductor L1, a capacitor C2, and a load (Z) are connected between each middle point of the switching elements S1 and S2 or S3 and S4. The switching elements S3 and S4 have an on-off timing range that is changed from the same phase to a 180-degree shifted phase with respect to a range of the switching elements S1 and S4. The concurrent on-state time of the switching elements S1 and S4 or S2 and S3 provided diagonally is changed so that the amount of power supplied to the load (Z) can be adjusted without shifting a switching frequency. Moreover, at least a switching frequency of the switching element S2 is made different than the other switching elements S1, S3, and S4 so as to supply a DC factor to the load (Z) while power with imbalance between the positive and negative is fed to a resonance circuit. Consequently, a discharge lamp, for example as a load, is prevented from going out and a flickering state with shifting strips is reduced.

Filed: 1994-11-15
Abstract: PURPOSE: To prevent the occurrence of excessive vibration during transition from slow-up to steady-state drive by using a point in time of the maximum angular velocity of a rotor when an exciting current is applied to a first exciting phase as a point in time of switching a next exciting phase. CONSTITUTION: Angular velocity is plotted on the axis of ordinate and a point in time of applied pulse is plotted on the axis of abscissa. A velocity line diagram A of a stepping motor indicates switching time point a to e of an exciting phase in a slow-up region. This switching time point means the point of the maximum angular velocity of a rotor when a predetermined exciting current pulse is applied to an exciting force. Therefore, a point where the maximum angular velocity occurs when a predetermined exciting current is applied to a exciting phase is used as the point for switching to the next exciting phase and this is made to sequentially continued in the same manner. Also, at a switching point d immediately shifting to steady-state drive region, the exciting current is also controlled to reduce the current so as to conform to the steady- state drive velocity.  Also, at e immediately after shifting to the steady-state drive region, a control to increase the current is performed so as to provide a predetermined exciting current required for steady-state drive.
