The upper half part of the front panel 11 is provided with a digital display control panel PCB12, a plurality of key-shaped switch caps 14 and a knob 15, and a metal sealing box 10 is arranged behind a digital display control panel PCB12, so that a shielding cover is effectively formed. The rear panel 41 is embedded with a fan cover 39, the fan cover 39 faces the air outlet of the fan 38, and the rear panel 41 is also provided with a ship-shaped switch 46, a Y-shaped three-way joint 43, a grounding column 47 and an external cable fixing clamp 44.
The EMC board PCB37 contains a two-stage filter circuit thereon. The right baffle 30 includes a ground post 47, and the ground post 47 forms a good shield together with the base plate 38 and the housing 2. The casing 2 comprises a grounding column 47, and the ground wire routing is sequentially a power wire and a ground wire, an EMC board PCB37, the casing 2 and the bottom plate 38.
As shown in the block diagram of the appliance shown in fig. 2. It can be seen that the welder is mainly divided into two loops: the first main loop is that the alternating current input is rectified to a first main loop PCBA after passing through an EMC board PCB 37; the output of the final electric welding machine is obtained by the PCBA of the main loop through the transformer, the PCBA of the second main loop and the output inductor; the other control loop is that the alternating current output is rectified by an EMC board PCB37 and then is output to a power supply board PCB; the power supply board PCB converts the power supply into a proper size to supply power for other control boards.
For the welder power supply, the main electromagnetic interference originates from both loops. The embodiment firstly adds an EMC circuit of two-stage filtering at the input of a power line; and meanwhile, an inductor and an output absorption board PCB are added at the secondary output of the main loop, and an absorption safety capacitor is added on the power supply board. Meanwhile, the main transformer and the power panel transformer are wound uniformly, and leakage inductance is reduced. And the two ends of the MOS tube, the I GBT tube and the fast recovery diode are respectively provided with a resistance-capacitance absorption circuit for reducing spike signals. Part of interference signals can be eliminated quickly through good grounding routing, namely power line ground wire → EMC board 37 → cover 2 and bottom board 28 in sequence. Both of these measures effectively reduce electromagnetic interference and electromagnetic susceptibility.
Such as the circuit schematic shown in fig. 3. Alternating current is input through an X capacitor C1 and then through a common mode inductor TR 2; after the first stage of filtering, the output of the filter is connected to a resistor R1 through an X capacitor C2 and a common mode inductor TR3, and then is connected to the ground through two Y capacitors C2 and C3. The circuit on the EMC board can effectively reduce the interference from the electric wire netting, can also effectively prevent the pollution of welding machine self to the electric wire netting. And by adopting the two-stage filter circuit, the effect is more obvious, and the cost is not too high.
The double pulse machine contains numerous high speed control signals. To enhance the electromagnetic sensitivity performance, the front panel 11, the rear panel 41, the bottom plate 28, the movable closing plate 3 and the housing 2 are first constructed to form a closed box. The main circuit and the control circuit are then separated by a right partition 30 to form two separate closed boxes. For the digital display control panel, the digital display control panel is wrapped by a dustproof sealing box. In addition, the control panel all uses four-layer board, with power signal and ground signal isolation for control signal, has strengthened the anti-interference performance of signal greatly.
