Title:
DIRECT CURRENT SWITCH ARC-EXTINGUISHING DEVICE SUITABLE FOR HIGH POWER
Document Type and Number:
WIPO Patent Application WO/2019/019602
Kind Code:
A1
Abstract:
A direct current switch arc-extinguishing device suitable for high power, comprising: a first direct current switch (J1), a second direct current switch (J2), a first diode (D1), and a second diode (D2); the first direct current switch (J1) is connected between a direct current positive input (Vin+) and a direct current positive output (Vout+), and the second direct current switch (J2) is connected between a direct current negative input (Vin-) and a direct current negative output (Vout-); the anode of the first diode (D1) is connected to the connection point between the second direct current switch (J2) and the direct current negative output (Vout-), and the cathode of the first diode (D1) is connected to the direct current positive input (Vin+); and the anode of the second diode (D2) is connected to the direct current negative input (Vin-), and the cathode of the second diode (D2) is connected to the connection point between the first direct current switch (J1) and the direct current positive output (Vout+). By means of the present invention, the current in an inductor (L) cannot change abruptly, a new path is sought for continuous flowing of the current by means of the first diode (D1) and the second diode (D2), and linkage is turned off so that the freewheeling path may implement energy being fed back to a direct current circuit, thereby achieving lossless recovery of energy; in addition, the device has a simple circuit, is easy to implement, has a small volume, and is low cost.
