Solution Overview
Problem
High-voltage power supplies lack the ability to controllably adjust output voltage to manage waveform effectively, which is crucial for applications like ion implantation, plastic curing, and medical imaging, where precise voltage control is necessary.
Innovation Solution
A system comprising multiple power stages and a controller that selectively operates these stages to adjust output voltage, allowing for incremental voltage increments and decrements, enabling the generation of high-voltage electrical energy up to several megavolts with controlled bipolar waveforms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If high-voltage power supplies are used for applications like ion implantation and plastic curing, then the power supply can deliver the necessary high voltage, but the ability to controllably adjust output voltage and manage waveform is insufficient
Solution Approach 1:
The power supply is divided into multiple discrete power stages that can be independently controlled. Each stage contributes a specific voltage increment, allowing the output voltage to be adjusted by selectively enabling or disabling individual stages. This segmentation enables precise waveform control and voltage adjustment without requiring complete redesign of the entire power supply system.
2Measurement precision
If multiple power stages are used to achieve precise voltage control, then output voltage can be adjusted incrementally, but the device complexity increases
Solution Approach 1:
The power supply system incorporates dynamic control capability where individual power stages can be selectively activated or deactivated based on the desired output voltage. This dynamic switching between stages allows precise voltage adjustment while maintaining a relatively simple overall structure, as the same physical stages can be reconfigured for different voltage levels without adding permanent complexity.

AI summary
Systems and methods presented herein generally provide for the controlled voltage of bipolar electrical energy through the selected operation of power stages. In one embodiment, a system that provides electrical energy includes a power supply and at least two power stages coupled to the power supply. The power stages are operable to selectively output electrical energy. By selecting the number of power stages which are turned on at a given time the total voltage of the electrical energy is controlled at that time. The system may further include one or more controllers coupled to the power stages to control selection of the power stages and thereby vary the output voltage.
