摘要： PROBLEM TO BE SOLVED: To provide a power conversion device that suppresses transitional biased magnetization of a transformer resulting from a voltage fluctuation without requiring any additional components.SOLUTION: A control circuit 13 decides a pulse width on the basis of a result of comparison of an output voltage of an output side circuit 12 with a voltage command, and controls switching of FETs 110-113 such that a pulse voltage having the decided pulse width is applied to a primary winding 100 alternately positively and negatively with time. Specifically, the switching of the FETs 110-113 is controlled such that the pulse width is updated every time the pulse voltage is applied three consecutive times. Biased magnetization of a transformer 10 can thus be suppressed even when an input voltage fluctuates. An existing capacitor for biased magnetization prevention is dispensed with. This can reliably suppress transitional biased magnetization of the transformer 10 without requiring any additional components.

摘要： PROBLEM TO BE SOLVED: To obtain a sensorless control method, in which the polarity of the field-system polarity of a rotor at a sensorless-controlled permanent-magnet field-system synchronous motor is judged also during its rotation, and whose controllability is enhanced. SOLUTION: In a sensorless control method, the phase current of a permanent-magnet field-system synchronous motor is detected at every control cycle, the position angle θ and the angular velocity ω of its rotor are computed, and they are fed back to control the permanent-magnet field-system synchronous motor. In the sensorless control method, the difference of the position angle θis computed, it is designated as ω' (Step 202). Then, the sign of the ω' is compared with the sign of the angular velocity ω computed on the basis of the phase current or the like of the permanent-magnet field-system synchronous motor (Step 203). When their signs are different, it is judged that the polarity of a field-system polarity is recognized erroneously, a phase correction in which a π radian is added to the position angle θ is performed to the position angle, and a sign correction in which the sign is inverted is performed to the angular velocity ω (Step 204).

摘要： PROBLEM TO BE SOLVED: To provide the control equipment of a PM motor wherein constitution is simplified, expensive apparatus like an insulated amplifier is unnecessary, and an error voltage due to dead time can be compensated with high precision. SOLUTION: A current sign recording circuit 3 for recording the current signs is installed in the control equipment of a PM motor which controls the rotation of a motor connected with an inverter. The current sign signal 331a showing the direction of, e.g. the U phase, is formed with a voltage comparator 331. Central timing of a dead time period following the rise and the fall of a switch control signal 92 controlling a switching element of the inverter 1 is formed with a delay circuit 321. The current sign signal is recorded, and it is inputted in an information processing part 2. The practical PWM duty is calculated with the information processing part. As a result, an accurate average voltage is calculated, and the calculated result is used for angle calculation or the like of a rotor.

摘要： PROBLEM TO BE SOLVED: To reduce a radiation magnetic field and inductance, which occur by a current path comprising bus bars in a three-dimensional module structure using the bus bars.
SOLUTION: A first bus bar 50 and a second bus bar 60 have parts which mutually become parallel. When a distance between the parts which mutually become parallel is smaller than a distance between a first connection point and a second connection point, or a distance between a third connection point and a fourth connection point; at least the first bus bar 50 or the second bus bar 60 is brought close to a first substrate 20 or a second substrate 30 so as to be made parallel. A direction of current flowing in the first bus bar 50 and a direction of current flowing in the second bus bar 60 become opposite. Mutual inductance which occurs by current flowing in the respective bus bars 50 and 60 reduces total inductance of the bus bar 50 and 60.

摘要： PROBLEM TO BE SOLVED: To provide a power conversion device that suppresses biased magnetization of a transformer owing to characteristic variations of components.SOLUTION: If there are any characteristic variations of FETs 110-113, a positive or negative DC component is included in a current flowing through a primary winding 100.

Specifically, a positive pulse voltage is determined on the basis of a positive current flowing through the primary winding 100 to control the positive current, and a negative pulse voltage is determined on the basis of a negative current to control the negative current. This can finally suppress the DC component to suppress biased magnetization of the transformer owing to the characteristic variations of the FETs 110-113.

摘要： PROBLEM TO BE SOLVED: To provide a semiconductor power converter wherein active gate control can be effectively carried out according to change in main circuit supply voltage. SOLUTION: A surge voltage target setting unit 103 acquires the main circuit supply voltage of the semiconductor power converter based on the terminal-to-terminal voltage Vce of a semiconductor switching element 100, detected by a voltage detection unit 102, and sets a control target Vm of surge voltage according to the acquired main circuit supply voltage. When the semiconductor switching element 100 is turned off and the terminal-to-terminal voltage Vce exceeds the control target Vm, an active gate control unit 71 carries out the following processing: it sets a voltage correction amount V1 (>0) so that the gate voltage Vg is corrected in such a direction as to increase the gate voltage Vg, that is, reduce the turn-off speed based on the feedback of the terminal-to-terminal voltage Vce.
