Filed:

May 3, 2000

Appl. No.:

09/563563

Inventors:

Jeffrey A. Perkins - Amherst OH
Joseph G. Schroeder - North Royalton OH

Assignee:

Nordson Corporation - Westlake OH

International Classification:

B05C 1100

US Classification:

118695, 118698, 118308, 700 17

Abstract:

Systems and methods for controlling, organizing, and viewing a plurality of electrostatic spray gun operating parameters from a centralized control panel are provided. In this regard, a control panel is provided having, for example, a gun control area for selecting one electrostatic spray gun of a multiple gun system, and an electrostatic control area for displaying and controlling the operational parameters of the selected electrostatic spray gun. The electrostatic control area functions essentially as a master control panel which can be shared by all the guns in the system. Each of the guns has an assigned gun control subpanel in the gun control area. Each subpanel includes a selector switch which can be used to monitor and control the gun associated with that subpanel on the master control panel. Each of the subpanels also has a limited display such as a bar graph which can be used to show the electrostatic performance of the guns. The subpanel displays are configured in a tight cluster so that the operator can easily simultaneously monitor the performance of all the guns in the system to identify any guns which are not performing properly.

International Classification:

H02M 324

US Classification:

363 98, 363 17

Abstract:

A current mode controller for a series resonant power converter having a primary current, a conduction time and a pulse width modulator controller is disclosed. The current mode controller having a current ramp generator in electrical communication with the primary current and being operative to generate a current ramp having a voltage proportional to the primary current. A voltage ramp generator is in electrical communication with the power converter and operative to generate a voltage ramp. The current mode controller further includes a multiplier in electrical communication with the current ramp generator and the voltage ramp generator. The multiplier being operative to generate a time-dependent current ramp having an amplitude proportional to the conduction period of the power converter. A limited voltage ramp generator operative to generate a limited voltage ramp is in electrical communication with the voltage ramp generator. In this respect, the current mode controller further includes an adder in electrical communication with the limited voltage ramp generator and the multiplier and operative to generate a controlling ramp proportional to the limited voltage ramp and the time-dependent current ramp.

US Classification:

239690, 239 67, 239 69, 239 71, 239703, 239708, 239695

Abstract:

A system and method of storing and reading parameter data associated with an electrostatic spray gun power supply is provided. The method includes, for example, the steps of reading parameter data associated with a power supply for a particular spray gun from a database and storing the parameter data in a memory device associated with the spray gun. The parameter data may include the drive current parameter information, for example, and additionally, spray gun type identification information. The memory device is preferably integral with the spray gun or a cable connector that connects to the spray gun. The data or information can be in the form of analog or digital information. After reading the spray gun power supply parameter data, the spray gun controller appropriately operates and monitors the spray gun to ensure that the spray gun power supply is performing properly.
