Technically, the Loop’s construction began in 1978. But it wasn’t called the Loop then. If you’re unfamiliar, the Loop is a 131-mile trail that spans Tucson, South Tucson, Oro Valley and Marana.

A control strategy for the active power decoupling in a single-phase full-bridge-based bidirectional dc–ac converter is proposed in this work. An ac-side auxiliary-circuit three-leg topology is used ...

For a single converter or a parallel system with multiple modules, the modeling and analysis of the control loop is very important. It determines whether the designed main circuit components can work ...
