摘要： To suppress a DC component in AC power in a power converter for converting DC power to AC power. DC power is converted to AC power by a converter 2, and the AC power is supplied to output terminals u1 and u2 via an inductor 3. The converter 2 is controlled based on an error Δ(t) between an output current ip(t) outputted from the converter 2 and a target current j(t) outputted from a target current generation means 110 as a target value for the output current ip(t), and a DC component VD in an output terminal voltage v(t) is detected by a voltage detection means 18. A DC component ID is suppressed by correcting a target current j(t) by a DC component suppression means 8. Also, a DC component in the AC power is suppressed to prevent biased magnification of a transformer 4 by calculating a correction amount jh(t) for correcting the target current j(t) from the difference between a first instantaneous value d1 of a load current is(t) flowing to a load 4 at a first time point t1 and a second instantaneous value d2 of the load current is(t) at a second time point t2 that is a half cycle after the first time point to correct the target current j(t).

摘要： A mounting of semiconductor laser chip on a heat sink or metal mount is improved so as to enable high accuracy of position and direction. A heat sink or metal mount, on which a semiconductor laser chip is mounted, comprises two parts, namely a main mount or larger portion and a sub-mount or smaller portion. The semiconductor laser chip is soldered by a solder layer on the sub-mount utilizing a microscope so as to assure an accurate position and an accurate direction with respect to the sub-mount. Then, the sub-mount is soldered on the main mount by a solder layer with an accurate relation both in position and direction by engaging a linear ridge as a first engaging means provided on the upper face of the main mount with a straight groove and a rear end face as a second engaging means. As a result of the above-mentioned structure, accurate position and direction of the semiconductor laser chip with respect to the mount is easily obtainable with a high yield.

摘要： A terrace-substrate laser is improved by forming a stripe-shaped impurity diffused current-injection region (27) from the cap layer (25) at least so as to reach the oblique lasing region (231) of the active layer (23), so that the corner part of the current injection region (27) touches the lasing region (231); thereby current injection efficiency to the lasing region is highly improved and the injected current is effectively limited in the oblique lasing region even when a large current is injected, and furthermore, a threshold current can be greatly reduced. This laser can perform a stable fundamental transverse mode oscillation even at a large current operation.
