A microgrid is a clear energy system consisting of demand management, storage, generation system and loads which are capable of operating in parallel or independently with the main power grid. There are some issues in the inverter circuit design which are, high frequency switching loss and noise. In addition, an electrostatic generator generates high voltage DC and low current. Any types of wave distortion...
The inverter is a power electronics device which changes DC voltage to AC voltage or vice versa. The synchronous phase inverter is used in the microgrid system to connect the renewable energy sources of minimum phase error. For a high-efficiency power transmission and distribution system, a three-phase inverter is used. The electronic switches of the inverter are controlled by a controller circuit...
The inverter is an electrical switching control device that can be converted from one source to another source like as DC to AC or AC to DC. An efficient three leg IGBT inverter has been designed for microgrid systems which are simulated by MATLAB2014a /Simulink. The inverter switches are controlled by a pulse controller, which mainly generates the switching gate pulse. The switching pulse controller...
The synchronous inverter is an electrical inverter device which is synchronizing inverter phase into the micro-grid phase at the same amplitude and frequency. A three phase phase synchronous inverter (PSI) is basically used in the high efficiency power supply systems. The inverter phase is depend on the controllers which are two level pulse width modulation (PWM) generator, phase lock loop (PLL) regulator,...
A three phase three layer phase synchronous inverter is a highly efficient, simple switching control of the power management system. Compared to conventional inverters, its output-waveform has less harmonic distortion. The phase synchronous inverter is designed using well-established theory and used in micro grid power systems. The switching logic control, phase synchronization, low pass filter and...
A piezoelectric micro-energy harvesting system is composed of piezoelectric transducer, rectifier, DC to DC converter and storage device. Parameters of the DC to DC converter have been optimized to harvest maximum energy from piezoelectric transducer. The key parameters are switching frequency, duty cycle, output load and inductance have been studied. The input voltage of the circuit from the piezoelectric...
