Abstract
An improved power supply for an electrostatic spray gun device having a voltage multiplier circuit adjusts to variations in the output load conditions of the multiplier circuit and dynamically modifies the operational loadline of the multiplier circuit in order to maintain optimal operating conditions for the spray gun device notwithstanding output load variations. The power supply utilizes a loadline manipulation circuit coupled to a feedback circuit that monitors the output load, and the manipulation circuit, in response to a feedback signal from the feedback circuit that is proportional to the output load, varies the input voltage level to the multiplier circuit to modify the loadline of the power supply in response to varying load conditions. The manipulator means of the power supply has memory means to store a variety of external commands which will control the manipulation means and a user interface to enter the external commands into the memory. The power supply also comprises a voltage limiting circuit coupled to the output of the multiplier circuit which regulates the output voltage level of the multiplier circuit so that when the output load current increases above a pred…
