PV powered modular pulse generator with embedded energy storage for tumour treating fields

Tumour Treating Fields (TTF) exhibit great potential as a standalone cancer treatment, primarily due to minimal side effects. The solid-state power converter is the main component, shaping voltage pulses to impose electric fields on cells. This converter should provide control and flexibility to target infected tissues without harming healthy cells. The proposed system is powered by renewable green energy, addressing the global warming crisis by reducing exhaust emissions. The system, built in a scalable three-stage modular form, can generate a wide range of voltage pulses. These stages include the interleaved DCDC Maximum Power Point Tracking (MPPT) converter assisted by embedded energy storage, and both powering the third stage, a full-bridge pulse generation converter. The system undergoes investigation through a MATLAB/Simulink case study for three cascaded modules. Additionally, each module operates under different conditions, demonstrating the system’s functionality and reliability. Results show the system rapid response, and it functions properly even though modules are operated and investigated under different conditions and operating points.
