Problem Statement
- Conventional power supplies and methods for achieving bipolar high voltage output are inadequate for applications requiring controlled, continuous bipolar voltage with lower dv/dt rates and reduced peak power.
- Complexity and Inefficiency: Existing solutions, involving series configurations of boost stages and output stages, are complex, inefficient, and primarily designed for pulsed load applications, making them unsuitable for steady-state bipolar HV requirements.
Technology
- The present invention relates to a system and a method for obtaining bipolar voltage output.
- The system uses first and second bidirectional converter modules, each featuring a bidirectional flyback converter and comparators, to achieve precise control of bipolar voltage output.
- A controller, executing instructions from memory, assigns positive and negative values to the respective converter modules based on a predefined reference voltage, ensuring accurate voltage output by operating in charge, refresh, or discharge modes.
- The method involves selecting and comparing present output voltage against the reference voltage for each converter module, dynamically adjusting operation modes to maintain desired bipolar voltage profiles.
