Device for the operation of loads on AC supply terminals
A device for operating loads from AC voltage sources has the following features in order reliably to reduce the cold switching-on current of loads and to ensure controlled switching of the loads: a) an AC voltage source, b) a first transformer whose primary winding is connected to the AC voltage sou...

| description | A device for operating loads from AC voltage sources has the following features in order reliably to reduce the cold switching-on current of loads and to ensure controlled switching of the loads: a) an AC voltage source, b) a first transformer whose primary winding is connected to the AC voltage source, c) a load which is connected to the secondary winding of the first transformer, d) a first switching device in the connection between the primary winding of the first transformer and the AC voltage source, e) a microcomputer which is connected to the control input of the first switching device in order to change the state of said first switching device, f) a series circuit consisting of a second switching device and a bias resistor in parallel with the first switching device, the control input of the second switching device being connected to the microcomputer in order to change the state of the second switching device, g) a drive circuit in the microcomputer for the first and second switching devices, which drive circuit initially switches the second switching device to the closed state when a switching-on signal for the load is present, and switches the first switching device to the closed state and the second switching device to the open state after a first delay time. |
