| titleOfInvention | Hardware anti-misoperation voltage-multiplying circuit with self-locking function |
| abstract | The application relates to the technical field of multi-voltage inverter electric welding machines, in particular to a hardware anti-misoperation voltage-doubling circuit with a self-locking function, which comprises a bridge rectifier filter circuit, a voltage-doubling rectifier filter circuit, a control sub-circuit and a protection sub-circuit; the bridge rectifier filter circuit is used for converting 380V alternating current three-phase network voltage into direct current voltage, and is in a bridge rectifier state at the moment; the voltage-multiplying rectification filter circuit is used for converting 220V alternating current single-phase network voltage into direct current voltage, and is in a voltage-multiplying rectification state at the moment, and the control sub-circuit is connected to the voltage-multiplying rectification filter circuit and is used for controlling the on and off states of the voltage-multiplying rectification filter circuit to realize the switching of a bridge rectification state and the voltage-multiplying rectification state; when the direct current voltage is larger than the threshold voltage, the protection sub-circuit automatically switches the voltage-multiplying rectification state into the bridge-type rectification state. This application has the effect that improves many net voltage contravariant welding machine job stabilization nature. |
