Abstract: A hood latch assembly comprising: a striker; a base plate having a striker guiding path; a latch secured to the base plate by a latch shaft, the latch being configured to rotate from an unlatching position to an over-rotation position across a latching position upon engagement with the striker; a latch spring configured to push the latch in an unlatching direction; and a ratchet secured to the base plate by a ratchet shaft, the ratchet being configured to engage with the latch returning to the latching position from the over-rotation position by spring force of the latch spring and to maintain engagement of the latch with the striker, wherein the latch has a ratchet contact arm including a straight portion, the straight portion of the ratchet contact arm being configured to contact a base portion of the ratchet when the latch reaches the over-rotation position.

Abstract: In a power supply device, the bridge circuit including a plurality of switching arms which is an inverse-parallel circuit of a semiconductor switch and a diode. The power supply device includes a control unit. The control unit switches the semiconductor switch such that a voltage v between AC terminals becomes a positive-negative voltage whose peak value is the voltage Vo between the DC terminals only during prescribed time periods before and after a point that has deviated from each zero crossing point ZCP of a current i by a prescribed compensation period ? and such that the voltage v between the AC terminals becomes a zero voltage during the other time periods, and sets the compensation period ? such that a time period during which the voltage v between the AC terminals becomes a zero voltage is the shortest.
