Title:
ELECTRIC POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/105133
Kind Code:
A1
Abstract:
In the present invention, a control device (20) controls an inverter (2) such that a detection value of an output current of the inverter (2) tracks a current command value (i*). The control device (20) is configured to compute a current deviation between the current command value (i*) and the detection value of the output current of the inverter (2) and control switching of switching elements (Q1-Q6) such that the computed current deviation is equal to or smaller than a current deviation command value (Δi*). The control device (20) provides a current limiter with respect to a load current (iL), the current limiter being smaller than an overcurrent level. When a detection value of the load current (iL) is larger than the current limiter, the current device (20) reduces the current deviation command value (Δi*) in comparison to when the load current (iL) is smaller than the current limiter.
