An additional transistor [T.sub.3] and a clamping diode [D.sub.2] are introduced into the circuit, as shown in Fig.
This configuration is an alternative to the diode clamped inverter; however, voltage across an open switch is constrained by clamping capacitors instead of clamping diode in diode clamped topology [8].
Moreover, clamping diodes, Da1 and Da2, have the same loss.
Utilizing built-in clamping diodes, the EMX7510 has the capability to sink up to 300 mA, making it suitable for driving and sensing external devices such as relays.
Out of these three structure, cascaded MLI its doesn't requires clamping diodes and flying capacitors and it require the lowest number of semiconductors switches to produce particular leveled waveform.
As can be seen in Figure 1 each bridge arm is composed of four anti-parallel diodes [S.sub.xy] (x = a,b,c; y = 1,2, 3,4) and two clamping diodes [D.sub.xy] (x = a, b, c; y = 1, 2), respectively.
Each leg has four switches and two clamping diodes. These diodes are connected to the capacitor neutral point (NP) for voltage clamping.
The former measures current flow through the parasitic diode junctions in a device (clamping diodes, substrate junctions).
