Abstract

The invention discloses a GTO (gate-turn-off thyristor) water-cooling inversion power module, belonging to the technical field of high-power semiconductor switches. The overall dimension of the module is 490*953*777 (unit: mm). The module comprises a metal aluminum alloy left support frame, a power string, a metal aluminum alloy right support frame, a cake-shaped water-cooling reactor, a connection copper bus, an N-phase output copper bus, a water-cooling resistor, a water-cooling resistor mounting plate, an M-phase output copper bus, an AC (alternating current) input copper bus, a copper bus insulating bracket, a 15[mu]f capacitor, a P-phase output copper bus, 2.5[mu]f capacitor, a pulse trigger plate, a water inlet main pipe, a water outlet main pipe and a capillary water pipe. The metal aluminum alloy left support frame and the metal aluminum alloy right support frame define a support main body in the invention, and are processed from aluminum alloy serving as a raw material by a mould casting method. The power string is mounted on the rear upper layer of the structure of the GTO water-cooling inversion power module, and the lower layer of the power string is provided with the water inlet main pipe and the water outlet main pipe. The pulse trigger plate is arranged behind the power string.

Description

technical field [0001] The invention belongs to the technical field of high-power semiconductor switches, and in particular provides a water-cooled inverter power module using a gate-turn-off thyristor (GTO) as a gate-turn-off thyristor (GTO for short). Water-cooled power modules for current control devices, suitable for GTO inverter power phase modules with water-cooled systems. Background technique [0002] The gate can turn off the thyristor GTO (Gate Turn-Off Thyristor), also known as the gate-controlled thyristor. Its main feature is that the thyristor can be turned off by itself when the gate is applied with a negative trigger signal. After the ordinary thyristor (SCR) is triggered by the positive signal of the gate, it can maintain the on state even if the signal is removed. To turn it off, the power supply must be cut off, so that the forward current is lower than the holding current IH, or the reverse voltage is applied to force it to turn off. This requires the ...
