Cell voltage=3.4V, Rg=47ohm, a capacitor with 22uf/25V, and DC/DC isolated is used for each half-bridge. For each half-bridge (except the last half-bridge used), the wire between the COM pin of "IR2103S" and the source pin of the low-side MOSFET switch is lifted as shown in Fig. Note that in Proteus software, I have used IR2104S instead of IR2103S (both of them are able to achieve the same function). A single IR2103S is used to drive each half-bridge while two of IR2103S are used to drive each full-bridge as shown in Fig. The type of the Half-bridge driver used is " IR2103S". Each module is connected to the next module (cascaded). Each cell is integrated with half-bridge (called a sub-module) while each pack of sub-modules is integrated with full-bridge (called a module). CadenceĀ® PSpice technology offers more than 33,000 models covering various types of devices that are included in the PSpice software. The type of the MOSFET used is "IRF530N". 2 is used here to simplify the circuit and to present the problem (let's focus on Fig.2 instead of Fig.1). I am trying to drive the MOSFET switches in a cascaded hybrid modular multi-level converter as shown in Fig.
