摘要
A power supply for producing complex non-periodic waveforms from a sum of periodic waveforms is disclosed. The power supply includes a controller which measures the output signal and compares it to the desired signal in order to produce an error signal. The error signal is fed to the power stage and is used to modify the input signal and produce the desired output. The desired signal is programmed by the user by selecting a plurality of pre-defined stored waveforms, modifying them, and arranging them such that the desired complex non-periodic waveform is created. The user can enter the instructions for modifying and arranging the waveforms via a panel having a keypad and display, or using a computer running software which enables the user to modify the stored waveforms on-screen. Such control is particularly useful in industries in which a very specific complex output signal is desirable, such as in the electrolytic plating industry. An optional process feedback system may be employed to monitor and respond to plating process variables.
