Converter Topologies

The conventional PWM converter topologies limit the operation to lower switching frequencies because of the minimum ON-time of the transistor switch. The quadratic feature is interesting for application where a wide voltage range is necessary, a quadratic buck-boost converter is presented. The converter cell is showed, the quadratic buck converter with the converter cell can convert to the quadratic buck-boost converter without increasing elements.

The development of switching converters to perform with the power processing of photovoltaic (PV) applications has been a topic receiving growing interest in recent years. This work presents a nonisolated buck-boost converter with a quadratic voltage conversion gain based on the I–IIA noncascading structure. The converter has a reduced component count and it is formed by a pair of L–C networks and two active switches, which are operated synchronously to achieve a wide conversion ratio and a quadratic dependence with the duty ratio. Additionally, the analysis using different sources and loads demonstrates the differences in the behavior of the converter, as well as the pertinence of including PV devices (current sources) into the analysis of new switching converter topologies for PV applications. In this work, the voltage conversion ratio, steady-state operating conditions and semiconductor stresses of the proposed converter are discussed in the context of PV applications. The operation of the converter in a PV scenario is verified by experimental results.

This paper proposes a high efficient advanced DC-DC converter by name Triple-Lift converter in the front end of Induction motor (IM) drives system. The conventional IM drives use PWM rectifier, boost converter, buck-boost converter, etc., in the front end which holds inadequacy in pump-up voltage and deprived output current. The Triple-Lift converter (TLC) implemented in the system employs voltage lift technique and produces the output voltage in arithmetic progression. The voltage source inverter (VSI) coupling IM derives a wide range of DC input (ripple free) from TLC which can be adopted for high rated motors with good efficiency. Simulation results using MATLAB show the effectiveness of the proposed converter arrangement for IM drives.

The prominence of Fuel Cell Electric Vehicles (FCEV) has been soaring in technologies being implemented in electric automobiles due to their main advantages of eco-friendly nature, bountiful efficiency and extreme reliability .In this paper we deal with the simulation of electric vehicles that are fuel cell based. The voltage at the output stack of fuel cell is considerably low, hence it is increased by rendering IDDB converter with closed loop control. This type of boost converter with closed loop control is also utilized to priorate the converter output voltage consistent regardless of the pressure levels in the fuel cell. The output of the boost converter is coupled to the inverter for developing AC to run PMSM. Gating signals are produced to the inverter by the use of Space Vector PWM technique and the inverter output is supplied to the PMSM drive by means of an LC filter in order to diminish the ripples in the inverter output . In this work, in order to achieve better performance above induction motors such as higher speed, torque efficiency PMSM drive has been proposed . The results are verified by simulation techniques using MATLAB/Simulink.
