成果简介	NOVELTY - The system has a modified H-bridge provided with four complementary switch pairs, two asymmetrical direct current (DC) voltage sources, two capacitors, and two diodes. A configuration of twelve switches (S1-S12) is arranged in six complementary pairs. A system topology provides a voltage gain of 2, where the configuration does not require an auxiliary circuit for balancing capacitor voltage for enabling self-balancing capability. The twelve switches form six complementary pairs, namely such that each pair operates in a complementary manner to generate discrete voltage levels for output. Two capacitors that operate as switched capacitors to maintain inherent voltage balance during inverter operation while eliminating the need for external voltage sensors or balancing circuits. USE - Switched capacitor 25-level inverter system for solar power applications. Can also be used in locomotives, mixers, low and medium-power DC-to-alternating current (AC) energy conversion applications. ADVANTAGE - The system achieves a high voltage gain using lesser system components, and provides a voltage gain of 2 for doubling the input voltage without needing additional boost circuits. The system provides a high gain, combined with a streamlined component layout to enable efficient power conversion in a compact setup. The system includes a minimal configuration of 12 switches, two capacitors, two diodes, and two direct current (DC) sources, which collectively enable the generation of 25 distinct voltage levels. The system reduces the component count, and simplifies the design and reduces overall costs while achieving high-quality, and stable power output. The system realizes self-balancing capability for capacitors without requiring any external circuit for maintaining voltage balance, thus enhancing the system's reliability and ease of operation.
