The hardware can be developed using available power switch modules from different manufacturers such as Semikron, Mitsubishi, and Fairchild. The power switches are available in discrete form to implement inverter system. The gate driver circuit is also available from different manufacturers. The control can be implemented using microcontroller, digital signal processors (DSP), dSpace, and fieldprogrammable gate arrays (FPGA). The control codes can be written in C/C++.Modern designs are using IGBTs particularly since the new generations of IGBT have progressively lower losses and the ability to switch higher DC voltages. such as: (i) generation of PWM drive waveform, (ii) monitoring the O/P voltage, (iii) inverter output current for

overload.and short circuit protection, (iv) phase and frequency locking of output and the input power supply, (v) supplying the gate driver stages with properly timed waveforms, etc., in addition to charger control functions.The PMLOM can perform precision oscillation task without exceeding the given limit on allowable average power dissipation. Performance parameters, such as the force, current etc. are experimentally assessed. The objective of this paper is to determine the forces for aluminium mover embedded with Rare Earth Permanent Magnet experimentally and analytically through FEMM software and develop a microcontroller based IGBT Inverter for its control. Also the theoretically calculated Toshiba states [5]: “The latest

washing.machines use inverter control for both washing and spindrying. Inverter control helps reduce wash/spin noise and vibration and enables a washing machine to adjust the amount of water and motor torque to suit the washload. IGBTs are used for motor drive, and microcontrollers for overall control. Power factor correction (PFC) with IGBTs is used in the power supply circuit to keep harmonics in the input current below the IEC limit.” The Toshiba The control module consist an applicationspecific integrated circuit (ASIC) board, the input and output interface boards, and the keypad. 3.5.3.1 PWM Inverter In the voltage source variablefrequency drive, the third stage is made up of an inverter, with the inverter switches being formed

The switching To generate the pulse of the required width, a microcontroller has to compare the desired (modulating) signal with the reference signal and set 0 or 1 on its output pins.Its function is to convert the 5 V PWM signals from the microcontroller into the highvoltage control pulses that power the motor. In this design, IGBTs with a freewheeling diode were chosen. Their good current characteristics and relatively high frequency response enable the designer to drive the motor efficiently with a 1620 kHz PWM frequency that is above the audible noise limit. Figure 22 shows a basic schematic of the inverter. Except for the described devices, the power stage at least 25 to 100 times higher than the fundamental output

Figure 5.2 shows a threephase inverter, which is the most commonly used topology in today's motor drives. The circuit is basically an extension of the Hbridgestyle singlephase inverter, by an additional leg. The control strategy is Mohamed Bakr, Ahmed Elsharabasy. Fig. 3.
