摘要： PROBLEM TO BE SOLVED: To solve the following problem: a conventional signal transmission device, which soft-switches a main switch Sm to an on state by controlling a delay time of the switching timing to the on state from the reference timing, has low controllablity of soft switching due to a variation between a switching command of the main switch Sm to an on state and switching of an actual switching state.SOLUTION: An operation signal gm of a main switch Sm is transmitted to a drive unit DU as a charging voltage of a capacitor 80 through a photocoupler 60. By adjusting a resistance value of a resistor 76, an error in a time interval is suppressed.

摘要： PROBLEM TO BE SOLVED: To solve the following problem: there is the possibility of impossible discharge control of a capacitor 16 when a vehicle has a collision.SOLUTION: A series regulator 40 steps down a voltage of a capacitor 16 and outputs the stepped-down voltage to a drive unit DU of a U-phase lower arm. A flyback converter FBd for discharge control outputs electric power to a drive unit DU of a U-phase upper arm with an output of the series regulator 40 as an input. When a collision is detected, a photocoupler 54 is turned off, so that the series regulator 40 is turned on and hence a U-phase switching element Swn is turned on. Also, a power supply switching element 64 of the flyback converter FBd for discharge control is on-off controlled, thus turning on and off a switching element Swp according to a change in the output voltage of a secondary coil 60b of a transformer 60.

摘要： PROBLEM TO BE SOLVED: To solve the problem of flow of overcurrents, when operating a charging switching element 30 that turns on the power switching element Sw by opening/closing between a power source 20 and the gate of a power switching element Sw.

摘要： PROBLEM TO BE SOLVED: To provide a power conversion apparatus whose cost is made smaller than that of a conventional one. SOLUTION: The power conversion apparatus 30 has a plurality of units, each unit including power conversion units 31, 32 for converting power supplied from a first power supply E1 (power supply) and for output of the converted power to an output apparatus, and controllers 3B, 3C (control operation device) for individually driving and controlling two or more switching elements Q1-Q6 configuring the power conversion units 31, 32. The plurality of units are each connected so that the basic potential of the controller 3B, 3C may be the same as the basic potential of the power conversion units 31, 32. This configuration can eliminate the necessity of providing an insulating element between the switching elements Q4-Q6, Q22 on the lower arm side and the controllers 3B, 3C, and manufacturing cost can be reduced as that much. Further, since the basic potentials of the controllers 3B, 3C are certainly the same as those of the power conversion apparatuses 31, 32, signal transmission between them can be unfailingly executed.
