Title:
電力変換システム
Document Type and Number:
Japanese Patent JP6838170
Kind Code:
B2
Abstract:
First to n-th (n is an integer of 2 or more) power conversion devices (U1 to Un) are connected in parallel to a load (52). First to n-th fuses (FS1 to FSn) are provided in first to n-th wirings (W1 to Wn), respectively. Each of the first to n-th power conversion devices (U1 to Un) includes a converter (1), an inverter (2), and a DC bus (L1 to L3) supplying a DC voltage from the converter (1) to the inverter (2), and capacitors (C1, C2) connected to the DC bus (L1 to L3). An i-th (1 ≤ i ≤ n-1) wiring (Wi) includes the DC bus (L1 to L3) of an i-th power conversion device (Ui) and the DC bus (L1 to L3) of an (i+1)-th power conversion device (U(i+1)). The n-th wiring (Wn) is connected between the DC bus (L1 to L3) of the n-th power conversion device (Un) and the DC bus (L1 to L3) of the first power conversion device (U1).
