This work demonstrates a simple home automation system that allows the user to control home appliances through wireless. Lights, air conditioners, electronic doors and fans are among the appliances that can be used in this system. In this system, the controlling and monitoring the appliances can perform in two methods. The first method is through a web server meanwhile the second method is by using...
This paper proposes a multiband isolation of Double Pole Double Throw (DPDT) switch with switchable transmission line stub resonators for applications of WiMAX and LTE in 2.3 and 3.5 GHz bands. The transmission line stub resonator used in this design is an open stub resonator with quarter wave of the electrical length. By using a simple mathematical model, the theory of the transmission line stub...
A standalone 3-phase half-bridge multilevel inverter with simple basic unit cells coupled to solar power generation is proposed. This proposed inverter is able to operate in either charging mode or inverter mode, which is suitable for solar power generation using photovoltaic modules. The active switches (power MOSFET) in this proposed inverter is operating at fundamental or twice the fundamental...
This paper presents a method of power conversion circuit topology for single-phase DC to AC boost converter by using sinusoidal pulse-width modulation (SPWM) technique. The presented circuit converter does not use a transformer to step up the voltage instead it use DC to DC boost converter and expected to be more efficient and lower cost compare with conventional converter in the market. The circuit...
A multilevel inverter with real-time switching angle calculation modulation method is proposed. This proposed inverter modulation method is able to operate in real-time mode and calculate the switching angles without complex algorithm or time consuming iterations. The active switches in this proposed inverter operates at fundamental frequency of the AC mains, resulting in lower switching losses. The...
