6 Energy-Saving Efficiency-Improving Engineering Your Solutions

7 Cascaded H-Bridge Vector Control Based on IGBT & IEGT 2-Quadrant & 4-Quadrant

8 Multi Winding Phase Shifting Multi-Pulse Rectifier

9 Modular Design AC-DC-AC PWM Control Ease of Maintenance Based on TI-DSP Digital Control Modbus/Profibus/TCP

10 The input terminals R, S, T are connected to the low voltage output terminals of the transformers secondary winding. The DC voltage is formed after being rectified by a three phase full-wave bridge rectifier and filtered by capacitors, this supplies the H bridge inverter circuit which consists of IGBT power cell modules using PWM control technology. The switch on and off actions of A+, A-, B+ & B- are controlled by fibre optic trigger signals. This is how the output voltage wave is formed.

Through control of the IGBT's, the energy from the load side is fedback to the grid side.

11 The waveform is formed from 5 power cells in this example. Excellent sinusoidal waveform and low dv/dt Output harmonic filter is unnecessary Suitable for many types of AC motors
