A new operation mode for a lateral unified-complementary BiCMOS (hereafter abbreviated as U-CBiCMOS) buffer driver based on a partially depleted CMOS/SOI process is proposed. The scheme utilizes a gated npn or pnp BJT inherent to a nor p-channel MOSFET. Forward current is applied to the base terminal of the channel MOSFET, with a normal pull-up or pull-down MOSFET as a current source, where eac...

In this paper, a macro-model of the proton exchange membrane fuel cell (PEMFC) stack is proposed. A comparative study is made by simulation for the proposed PEMFC macro-model and a reported PEMFC impedance model, which use for PEMFC dynamic a transfer function and an electrical circuit, respectively. The macro-model approximates the theoretical PEMFC current–voltage characteristic by a controll...

The current control methods play an important role in power electronic circuits, particulary in current regulated PWM inverters which are widely applied in ac motor drives and continuous ac power supplies where the objective is to produce a sinusoidal ac output. The main task of the control systems in current regulated inverters is to force the current vector in the three phase load according t...

This paper presents a model predictive control (MPC) of a utility interactive (UI) single phase inverter (SPI) for a photovoltaic (PV) system at residential/distribution level. The proposed model uses single-phase phase locked loop (PLL) to synchronize SPI with the grid and performs MPC control in a dq reference frame. SPI model consists of boost converter (BC), maximum power point tracking (MP...

The simple Selective Harmonic Elimination (SHE) for 3-Phase Voltage Source Inverter (VSI) is presented here. The proposed work is to examine the Selective Harmonic Elimination (SHE) and to eliminate harmonics produced by Pulse Width Modulation (PWM) inverter. The selective harmonic elimination method for three phase Voltage Source Inverter (VSI) is generally based on ideas of opposite harmonic ...

The impedance networks increment the input DC voltage of the voltage source inverters. Their advantage is lack of the additional switches – they use only inverter bridge switches. However they cause some side effects in the inverter operation. Up today the tips how to design Z-Source impedance network keeping it in the Current Continuous Mode are rare in the literature. The paper present proble...

The phase synchronous inverter is an electrical inverter device which is synchronizing inverter phase with the micro-grid phase. Generally, DC voltage supply is considered as the input of the DC to AC inverter which is a renewable energy source such as solar panel, wind turbine and battery storage, etc. The three phase three layer phase synchronous inverters are normally utilized in the high po...

Multilevel voltage source inverter has been recognized as an important alternative to the normal two level voltage source inverter, especially in high power application. Using multilevel technique, the output voltage amplitude is increased, switching devices stress is reduced and the overall harmonics profile is improved. Three presentable topologies can b considered for multilevel inverter (ML...

Two types of prime movers are continuously applied for rotating machinery: mechanical and electric drives. This tutorial focuses on electric drives, which are actually composed of separate components: electric motor, frequency converter (optional), and electric network including transformers. The main aim of this tutorial is to explain the phenomena of electric drives related to the torsional v...

This paper focuses on the modeling of a cage induction machine drive under direct-field oriented control, also referred to as flux-vector control. The interest is to create a behavioral model of an induction machine drive under field orientation for sytem simulations since field-oriented control is now commonplace in commerical adjustable speed drives. First, the 3phase induction machine model ...
