Design considerations for the improved Class-D inverter topology

The characteristics of the improved Class-D inverter and its optimal design considerations are described. Analytical considerations and equations are presented to provide easy-to-use design tools. A theoretical description for the design of the turn-off snubber capacitor, the overvoltage clamping snubber capacitor, and the damping resistors is explained. The validity of the theoretical description is verified by experimental results.
