Engineering Contradiction Analysis
1Adaptability or versatility
If multiple switch devices are connected in series and parallel to generate high-voltage pulses, then the versatility and modularity of the pulse generation circuit are improved, but the difficulty of synchronous control and circuit isolation increases
Solution Approach 1:
The patent introduces magnetic isolation components (transformers) as intermediaries between the control circuit and the multiple switch devices. These transformers provide magnetic coupling for signal transmission while maintaining electrical isolation, solving the circuit isolation difficulty when connecting multiple switch devices in series and parallel configurations.
Solution Approach 2:
The patent divides the control system into isolated segments, with each switch device controlled by its own isolated drive circuit. This segmentation allows each module to operate independently while maintaining overall system coordination, enabling both versatility and modularity without compromising circuit isolation.
