Z-source inverter for adjustable speed drives

Boost Converters for Gas Electric and Fuel Cell Hybrid Electric Vehicles

“…Technology for the two traditional inverters, which are voltage-source (V-source) inverters and current-source (I-source) inverters, had been advanced by the invention of the Z-source inverter, which employs an impedance circuit to couple a power source to the input of an inverter [2,3]. The Z-source inverter provides a power conversion process that may be used to synthesize waveforms with voltages above as well as below the source voltage.…”

“…Its inductor must handle the entire current, which is responsible for its main cost. The new Z-source inverter technology [2,3] boosts voltage directly by actively using the zero state time to boost the voltage. In the traditional pulse width modulated (PWM) inverter, this time is used only to control the average voltage by disconnecting the supply voltage from the motor.…”

“…It is called a Z-source inverter [2,3] and it adds a network of impedance to eliminate the problem of shoot-through. Shoot-through, which shoots the supply voltage through an inverter's upper and lower semiconductor switches, destroys the switches and it must be prevented by time delays in the control circuit.…”

ESL-𝚪-Z- Source Inverter

“…In recent years, various Z-source inverter (ZSI) topologies have been presented in numerous diversified studies [1][2][3][4]. Some of the studies are focused on modeling and control [5][6][7][8], modulation strategy [9][10][11][12], applications [13][14][15][16], and the development of new topologies [17][18][19][20][21][22][23][24].…”

Multiphase Z-source inverter using maximum constant boost control

“…Indeed, it was proved that the classical inverters have some drawbacks in contrast to the Z-source inverter topologies. These drawbacks can be summarized as follows [1][2][3][4][5][6]:…”
