The implementation of maximum power point tracking (MPPT) schemes by the ripple correlation control (RCC) algorithm is presented in this paper. A reference is made to single-phase single-stage multilevel photovoltaic (PV) generation systems, when the inverter input variables (PV voltage and PV current) have multiple low-frequency (ripple) harmonics. The harmonic analysis is carried out with ref...

Fuel cell technology is continuously gaining ground in E-mobility applications. cells require a constant supply of pressurized air, for which high-speed turbo compressors with air bearings are an optimal choice to reduce size, guarantee oil-free operation required the lifetime fuel cell, and increase efficiency. However, inverter driving electric motor compressor does not scale down increasing ...

Abstract-A new control approach for three-phase gridconnected inverters is presented. The inverter stage is a standard three-phase half bridge. During each 60° of line cycle, the three-phase half bridge can be de-coupled into parallel-connected a dual-buck inverter. Based on Onecycle control, a Unified Constant-frequency Integration controller (UCI) is proposed for the dual-buck inverter. The c...

The class Φ2 inverter is a new switched mode type of resonant inverter. This inverter is applicable for very high frequency application. In this paper, it proposes class Φ2 inverter reduced the voltage stress, and improve the dynamic response. The class E resonant inverter is not suitable for high frequency application, because it produce high voltage stress across the switch. The suitable ball...

Received Apr 29, 2012 Revised Jan 7, 2013 Accepted Jan 24, 2013 Multilevel inverters can reach the increasing demand for power quality and power ratings along with lower harmonic distortion and lesser electromagnetic interference (EMI). As the number of levels increases, it is important to control more switches in parallel with their concurrent processing capability. In this paper space vector ...

In this paper we present a 2 input analog Current-Starved Pseudo-Floating Gate (CSPFG) inverter with capacitive feedback. The analog CSPFG inverter suppresses low frequencies due to the active, local feedback. This inverter can be used in designing filters where a narrow band pass or reject is the main goal. Typical applications are detection of high frequency components in sensor signals, i.e....

ABSTRACT: New symmetrical multilevel inverter topology with reduced number of power electronic switches is introduced in this paper, which results in reduction of installation area, converter cost, losses, and have simplicity of control system. The proposed topology consists of series connected sub multilevel inverter blocks. Principles of operation and switching functions are well analyzed. Si...

In case of low voltage (12 to 24V) solar and battery powered sinus inverter applications a special converter topology for managing the high input current rating is required. Conventional solutions uses paralleled power MOSFETs to realize high current (several 100A) switches. In this paper a synchronized multi phase PWM concept was chosen to rise the over all efficiency of the inverter. In gener...
