21 Diodes in Series & Parallel | Power Electronics

The video tutorial covers the connection of diodes in series and parallel, focusing on the challenges and solutions associated with each configuration. In series connections, diodes are used to increase reverse blocking capability, but manufacturing tolerances can lead to uneven voltage sharing. Balancing resistors are introduced to mitigate this issue. In parallel connections, diodes are used to increase current capacity, but mismatches can cause uneven current distribution, leading to potential damage. The use of resistors in series with diodes is discussed as a solution to balance current distribution.
