The interleaved dc-dc boost konverter topology will reduce input current ripple, output voltage ripple, and current stressed on switching component, hence this konverter can be implemented for high power konverter and high voltage output. The performance comparison between interleaved dc-dc boost konverters with conventional boost konverter will be simulated by PSIM software. Both of dc-dc konverters with 1kW power, 60 volt of input voltage, and 300 volt of output voltage will be verified.

Wind Power Plants are pollution free so that it could address the environmental issue and the availability of renewable energy sources, hence this research supports the programs of the local government. Padang to be the shed of the renewable energy. The purpose of this research is to make a low capacity (micro) wind turbine which could help on supplying the electricity and could operate in areas with low wind speeds and can be set up on the houses' roofs. The methodology that is used to reach the purpose is an experimental method with steps consist of gathering wind data on the field, wind turbine design, the election of materials, manufacturing of the materials, and test of the tools. Padang city in West Sumatera is a city with low wind velocity, around 2-7 m/s, therefore the appropriate type of wind turbine is the Savonius type because it could spin in low wind velocity with the starting speed could happen on the velocity of 2m/s and very simple construction. The design that is made is 2 Savonius blades with overlap construction between both blade, the purpose is to utilize the reverse wind pressure from one blade to another and vice versa to increase the spin of the rotor. The Savonius is planned to be 4 stories. The materials that are used for turbine blade is aluminium and hollow axis type. The generator that is used is Panasonic 400 Watt permanent magnetic generator that could generate power on low rotation (150rpm); To enhance the rotation that reaches the generator, belt, and pulley transmission system is used with transmission comparison of 5: 1. Thus, bearing type that is used is a ball bearing. From the test result, the maximum power of 7,7 Watt is obtained with the rotor rotation of 340 rpm and wind velocity of 5,68m/s and Cp 0.3.

The simple method is introduced to understand the concept of grid connected systems. A phase Lock Loop (PLL) method estimates the phase-angle of grid system. The output of PLL is used to defines Iref , and the current of inverter becomes a feedback (IL). Both current are derived to produce PWM using current mode controller method. As long as the grid system on fault condition like voltage distortion, therefore the single-phase inverter that connected into the grid should change the role and keep stabilization. The voltages sag and swell are the possible conditions that occurred on a power system. Voltage Sag is an event where the line voltage decreases from the nominal line-voltage for a short period of time. Voltage swell is the event when the line voltage increase from the nominal line voltage. By using PSIM software, the injection and absorption of power into a grid system is verified during a voltage ...
