“…The SPWM approach employs a changing pulse at the power device's gate [9]. For a single-phase H-bridge inverter, two pulse width modulation techniques, namely bipolar sinusoidal pulse width modulation (SPWM) and unipolar SPWM, are typically employed to adjust the magnitude and frequency of the inverter's output voltage [10]. They represent the SPWM technique for harmonic reduction and show how to generate a SPWM switching signal using different simple operational-amplifier (Op-Amp) circuits/analog circuits for the three-phase pulse width modulated (PWM) voltage source inverter (VSI) [11].…”

With the extinction of fossil fuels and high increase in power demand, the necessity for renewable energy power generation has increased globally. Solar PV is one such renewable energy power generation, widely used these days in the power sector. The inverters used for power conversion suffer from power losses in the switching elements. This paper aims at the detailed analysis on switching losses in these inverters and also aims at increasing the efficiency of the inverter by reducing losses. Losses in these power electronic switches vary with their types. In this analysis the most widely used semiconductor switches like the insulated gate bipolar transistor (IGBT) and metal oxide semiconductor field effect transistor (MOSFET) are compared. Also using the sinusoidal pulse width modulation (SPWM) technique, improves the system efficiency considerably. Two SPWM-based singlephase inverters with the IGBT and MOSFET are designed and simulated in a MATLAB Simulink environment. The voltage drop and, thereby, the power loss across the switches are compared and analysed. The proposed technique shows that the SPWM inverter with the IGBT has lower power loss than the SPWM inverter with the MOSFET.

“…The two technologies that are going to change the future of electrical power production are renewable energy sources and power electronics. DC-link inverter is advantageous in renewable energy applications like grid tying of solar PV system and wind energy systems and also in adjustable speed motor systems due to its simplicity in both power stage topology and control strategy [1][2][3].There are three major techniques used for solving a problem. They are experimental, analytical and numerical methods [4].…”

This paper presents the comparison between various numerical methods namely Euler's Method, Midpoint Method, 2nd order Runge Kutta Method and 4th order Runge Kutta Method with the analytical method to solve a power electronic system in both single phase and three phase configuration using decoupled methodology. The values of source current, load current and DC link voltage are obtained for each method using Matlab software and compared with each other. Also, the error in each numerical method with respect to analytical method is calculated and tabulated. These power electronic models could be an excellent research platform for testing the renewable energy systems without going for full scale or scaled down models.

“…Opto-isolators can also isolate the PIC16F883 control circuit, which operates at a 5 V level, from the high DC voltage applied for the inverter circuit. The desired DPWM pulse trains generated from the PIC16F883 are transmitted to the logic circuit unit, which is designed to generate two complementary signals from each DPWM signal.TLP250 opto-isolators accept four low-power signals and output the appropriate highcurrent gate drive for the MOSFETs placed in the inverter circuit[65].As shown inFigure 4.13, when pin P1D is modulated to output DPWM signals while P1B is placed in its inactive state, pin 3 and pin 4 of CD4081 output two complementary DPWM trains to drive MOSFET Q1 and Q2. Pin 10 of CD4081 outputs high level to keep Q3 ON, and pin 11 of CD4081 remains low level to maintain Q4 OFF through TLP250.…”

A novel short-circuit self-heating (SCSH) control system was developed in this thesis to achieve the preheating of lithium-ion (Li-ion) batteries operated in extremely cold weather (<-30°C). The proposed system relies on the internal resistance of batteries and the short circuit current to heat up batteries using Joule heating. Experiments show that the SCSH control system can heat up the commercial Panasonic 18650 Li-ion batteries from-30°C to 0°C in 43 seconds, with less than 5 percent of the battery capacity consumed. The proposed heating system outperformed both external convective air heating and alternating current (AC) heating, in terms of heating time and energy consumption. Furthermore, a DC to AC battery power inverter was developed to implement the AC heating and to make the battery pack available for household appliances. This inverter employs a microcontroller using the direct pulse width modulation (DPWM) technique. The inverter achieves power output at various frequencies through programming, without changing the design of the circuit board. The optimal frequency ratio can be obtained theoretically, validated through MATLAB simulation, and was further examined through experimentation. The selected frequency ratio enables the DPWM signals to stimulate the designed inverter to produce high quality sinusoidal voltage.
