Title:
POWER CONVERSION DEVICE, POWER CONVERSION CONTROL DEVICE, POWER CONVERSION METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2011/158947
Kind Code:
A1
Abstract:
With regard to a device for supplying power from an MERS (magnetic energy regeneration switch) (100) connected to a power source (VS), the load current flowing from the MERS (100) to a load is detected by means of a current detecting unit (300a). For the purpose of forming a path to begin charging the capacitor (CM) of the MERS (100), a control unit (400) determines, on the basis of the detected load current, the timing for turning off the reverse-conducting type semiconductor switch of the MERS (100). The control unit (400) controls the maximum value of the voltage between both terminals of the capacitor (CM) by turning off the reverse-conducting type semiconductor switch of the MERS (100) at the determined target timing.
