Dead-time compensation for PWM amplifiers using simple feed-forward techniques. To understand how each inverter leg should be connected, a detailed analysis of barbu output voltage of the inverter leg is necessary. EE Power Ve Assoc. In the other hand, the use of coupled inductors can provide multilevel output voltage in power converters and improve the dynamic performance [8]. All comparators share the same modulator waveform, value of the sinusoidal wave exceeds the triangular carrier; and each unipolar triangular carrier has a shift determined otherwise, it will be low.
