摘要： A voltage control operation unit (106) receives, from a subtraction unit (104), a value obtained by subtracting a detection value of a voltage (Vm) from a voltage command value (VR), and performs a control operation for setting the voltage (Vm) to be equal to the voltage command value (VR). The voltage control operation unit (106) outputs the calculated control amount as a current command value (IR). A current control operation unit (110) receives, from a subtraction unit (108), a value obtained by subtracting a detection value of a current (IL) from a current command value (IR), and performs a control operation for setting the current (IL) to be equal to the current command value (IR). A driving signal generation unit (112) generates a signal (PWC) for driving a boost converter based on a duty command value (d) received from the current control operation unit(110).

摘要： A four pole, three-phase, NPC converter that produces virtually no common mode voltage. The low common mode voltage output is achieved by constraining the switch states of the NPC converter. A fourth pole and associated control balance the upper and lower DC link voltages. The converter may be an inverter or a rectifier.

摘要： An inverter circuit (24) includes a bridge circuit consisting of a plurality of pairs of a high-side switching element (T1, T3, T5) and a low-side switching element (T2, T4, T6), a command signal processing section (50), a pulse generating section (56) for generating pulse signals to control the inverter bridge circuit according to the command signal to have a dead time to prevent short circuiting of the dc power source and a command signal compensation section (54).

摘要： A microcomputer (11) includes a rotation angular velocity computation section (35), a feedback gain determination section (36), and a dead time compensation amount determination section (40). The rotation angular velocity determination section computes the rotation angular velocity (ω) of a brushless motor (2). Based on the rotation angular velocity, the feedback gain determination section determines feedback gains (Kdp,Kdi,Kqp,Kqi). The dead time compensation amount determination section determines a dead time compensation amount (βx). The greater the absolute value of the rotation angular velocity, that is, the higher the rotation speed of the brushless motor, the greater the feedback gains determined by the feedback gain determination section become, and the higher the responsivity of the feedback gains becomes. The greater the absolute value of the rotation angular velocity, the smaller the dead time compensation amount determined by the dead time compensation amount determination section becomes.

摘要： A closed loop pulse width modulator (PWM) inverter (50) corrects for variations and distortion in the ouput AC voltage (52) waveform caused by non-linearities of the switching devices (S1-S6) or changes in the DC link voltage (3). A signal is generated that is a volt-seconds representation of the voltage error between a voltage command signal (25) and the actual AC output voltage (52) of the PWM inverter (50). The volt-seconds error signal becomes a controlling signal means in the closed loop of the PWM inverter (50) to regulate the output AC voltage (52) of the PWM inverter (50). Another signal that represents changes in the DC link voltage (3) also modifies the voltage command signal (25). The system will compensate for the non-linear behavior of the PWM inverter (50) due to deadtime, minimum on-times and off-times, and DC link voltage (3) variations and voltage drops across the switching devices (S1-S6), and will also allow the operation of the inverter (50) in a linear fashion for the region of operation when one or more of its phases are saturated, i.e., either fully on or fully off.
