摘要: A controller (10) includes subtracters (101, 105), a command value corrector (103), and a control block (102). The subtracter (101) obtains a deviation (Δv0) of an output voltage (v0) applied from a switching power-supply circuit (61) to a second load (Cdc+Load) with respect to its command value (v0*). The control block (102) performs PI control on the basis of the deviation (Δv0) to generate a command value (idc*) for a current (idc) flowing in a coil (Ldc). The command value corrector (103) corrects the command value (idc*) such that high-frequency components of a current (iL) flowing in a first power-supply line (21), with respect to the fundamental frequency of an input current (iu1, iv1, iw1), are consumed in the switching power-supply circuit (61). The subtracter (105) obtains a deviation (Δidc) between the corrected command value (idc*) and the current (idc). Commands (r1, r2) for switches are generated on the basis of the deviation (Δidc).

摘要: In a power converter including a V connection inverter circuit, harmonic components included in output voltage are reduced to achieve a reduction in a loss of a load, such as a motor.Operation of four switching elements (a3 to 3d) of a V connection inverter circuit (3) is controlled so that the locus of a flux vector λp on a complex plane created by using voltage vectors Vp obtained by the operation of the switching elements (3a to 3d) approaches to a circle. Specifically, in order to create the locus of the flux vector λp close to a circle by using at least three of the four voltage vectors Vp, output sequences and output periods of the voltage vectors Vp are determined.
