One of the most important features of the TSI system is the disconnect capability. The TSI inverter has at least 3 disconnection levels in series (i.e. relay, fuse…) on each power port, as well as a galvanically isolated dual communication bus. The communication is thus fault-tolerant, each bus is capable of independently ensuring synchronization, load sharing and data communication.
The inverter module has two inputs – one for connecting to the DC network and the other for the AC network. When powered from the DC network, the module works like a classic inverter. In the EPC (Enhanced Power Conversion) mode, the load is supplied from the AC network. Despite all the disturbances (harmonics, ripples, short spurious impulses) usually transmitted by the network, a pure sinusoidal voltage is supplied to the load, even if the load is not linear. Pure sine wave at the output and ideal power factor at the input are achieved without drawing power from the DC source. With the TSI concept, current and voltage filtering is similar to that of a rectifier in combination with an inverter (on-line mode), but with significantly better efficiency.
