A three-phase inverter system is operating at an output power level ranging from 10kW to above 300kW, used in commercial and decentralized utility-scale applications. High output power can be realized through stacking multiple medium-power blocks.
The SE14.4KUS, SE43.2KUS and SE33.3KUS three phase inverters have three pairs of DC inputs and the three phase inverters with synergy technology have three pairs of DC inputs per unit, allowing to connect up to 3 strings per unit without the need for an external combiner box.
The extended power and commercial three phase inverters are provided with an integrated DC Safety Switch and with terminal blocks for the connection of three strings per unit, eliminating the cost of an external DC combiner box.
Considering inverter states in which one switch in each half-bridge is always on (for current continuity at the load) there are 23 = 8 switch state possibilities for the 3-phase inverter. We give each state a vector designation and a associated number corresponding to whether the top or bottom switch in each half-bridge is on.
Three-phase string inverter systems convert the DC power generated by the photovoltaic (PV) panel arrays into the AC power fed into a 380 V or higher three-phase grid connection.
However in three-phase inverters , this voltage is distributed across three phases to create a balanced three-phase AC output . There are two primary conduction modes in both single-phase and three-phase inverters i.e.. 120-degree conduction mode and the 180-degree conduction mode.
