In normal speed control of induction motor has been easier by using of microcontroller and semiconductor devices. This project is used to vary the pulse width modulation (pwm) signals by using arduino controller. The firing pulses of IGBT’s are varied .the firing pulse is given to the driver board and control the pulses. Speed control of a single phase induction motor is implemented using Arduino Uno controller. Arduino Uno controller is connected to the PWM inverter. The single phase inverter using arduino output will be compared
This project is to design a Step up DC DC Converter based on Three Winding Inductor using PIC Microcontroller. The pulse can be generated using PIC Microcontroller.
A quadratic boost converter topology based on a high conversion ratio dc to dc converter with an active zero-voltage switching (ZVS) snubber circuit is developed for PV system application. The snubber circuit is used to protect the device and also provide smooth switching. The re-boost inductor, a coupled inductor and charge-pump circuits are proposed to achieve the high voltage gain with quadratic function. A first inductor is proposed to re-boost the voltage gain to make the output voltage is higher. The converter operating principle of the proposed conversion system is described in the detailed converter analysis. Simulation and experimental results are used to verify the performance of the quadratic boost converter with the maximum power point tracking controller (MPPT) in the PV inverter system.
An increasing the switching frequency can improve the dynamics of power converters, but the efficiency may be degraded. Vary the efficiency and dynamics of power converters is a concerned in power electronics. This converter has two buck cells one works at high frequency and another works at low frequency. It works that current in the high-frequency switch is diverted through the low-frequency switch. The converter operates at very high frequency without adding control circuit’s .The switching loss of the converter remains small. This project is increased the steady state and transient response with low switching losses. Double frequency buck converter voltage is depends on the high frequency buck cell parameters, and is independent of the low-frequency buck cell parameters. This DF buck converter greatly improves the efficiency and exhibits nearly the same dynamics as the conventional high-frequency buck converter. This project can be extended to other dc–dc converters by the double frequency switch inductor and three terminal network structure.
The dc-dc power converters are gaining more attention in the power electronic research field. To cross the voltage demand, single input and multiple output topologies (SIMO) are developed. So many converters are available under this category. Integrated Dual Output Converter (IDOC) is one of the single input multi output topologies. IDOC is a DC-DC power converter which performs both buck and boost operations. The single power supply is used both simultaneously. The both of the switches in the IDOC can be connected in series. And operated to obtain the boost and buck voltages. In this project, the basic operation of IDOC is presented and compared with conventional buck converter. The hardware of IDOC with 100W is developed and tested. Also the experimental results are compared with the simulation results. Also the performance comparison among buck, boost and IDOC converters are tested.
