Title:
DEVICE FOR CONTROLLING POWER CONVERSION CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2018/190076
Kind Code:
A1
Abstract:
Provided is a device for controlling a power conversion circuit, wherein current distortion is suitably suppressed. In a first limiter 5, a voltage compensation component dVi_FF is limited to within the absolute value range of a switching level dV_level of a compensation voltage. A value Vdc/(Tc/2) for which a DC power supply voltage was divided by the half cycle of a triangular wave carrier signal is multiplied by the average value of an ON delay time dT_on and an OFF delay time dT_off, and an average value dVt_FB_ave of an error voltage component is outputted. In a second limiter 6, a value exceeding the absolute value of the switching level dV_level of the compensation voltage is extracted from the average value dVt_FB_ave of the error voltage component. A post-limiting voltage compensation component dVi_FF_b and a post-limiting error voltage component dVt_FB_c are added together, and a composite voltage compensation component dV_mixed is outputted.
