INVERTERS The device that converts dc power in ac power at desired output voltage ar frequency is called an inverter. 1. Single phase voltage souro inverters LIN 10. Current commutation: In this process, a current pulse is forced in the reverse direction through the conducting device. Now the net current (forward and reverse current direction devices) becomes zero and the device is turned off. 11. Load commutation:In this process, the load current flowing through the device either becomes zero or is transferred to another device from the conducting device. 13. Harmonic Factor: It is defined as the ratio of the total harmonic content to the fundamental component. A city police department and a gang of drug dealers play a game every day where the police must decide whether to focus their department resources on either street patrol or parks patrol, and the drug gang must make the same decision regarding where to focus their drug selling activities. If both focus on street sales the police make 90 arrests and the dealers avoid 10 arrests. If both focus on park selling. The police arrest 80 dealers and 20 dealers avoid capture. If the PD focuses on streets, while the DDS focus on parks, 5 arrests are made and 95 dealers escape arrest. If the PD focuses on parks while the DD focus on streets, then 10 arrests are made and 90 dealers get away. a) Find the Nash equilibrium in mixed strategies for the police department and for the drug dealers. b) Explain in simple terms what will play out in this game between the PD and the DDs. c) If the PD gets better at park patrol (measured by more arrests in parks than before), in which direction will the mixing strategies change? Explain. (It is not necessary to re-calculate answers 2 use economic logic)
