Japan, Feb. 24 -- TDK CORP has got intellectual property rights for 'POWER CONVERSION DEVICE AND POWER CONVERSION SYSTEM.' Other related details are as follows:
Application Number: JP,2021-164651
Category (FI): H02M3/28@P,H02M3/28@G
Stage: PROBLEM TO BE SOLVED: To obtain a power conversion device capable of setting charging characteristics in a precharge operation by a simple configuration.SOLUTION: A power conversion device has a first power terminal, a switching circuit having a plurality of first switching elements which can be turned on and off based on a first driving signal, a transformer, a rectification circuit having a plurality of second switching elements which can be turned on and off based on a second driving signal, a smoothing circuit, a second power terminal, and a control circuit. The control circuit, in a first period before supplying power from the first power terminal to the second power terminal, generates a first threshold value increasing as time elapses, and when a voltage value of voltage in the first power terminal reaches the first threshold value, performs switching from an output state of outputting the second driving signal to an output stop state of stopping the output of the second driving signal, or switching from the output stop state to the output state.SELECTED DRAWING: Figure 6 (Grant)
