6 FAQs about [Photovoltaic inverter lgbt module]

Are insulated-gate bipolar transistors a good choice for solar inverter applications?

For solar inverter applications, it is well known that insulated-gate bipolar transistors (IGBTs) ofer benefits compared to other types of power devices, like high-current-carrying capability, gate control using voltage instead of current and the ability to match the co-pack diode with the IGBT.

What is a solar inverter?

solar inverter is a power-electronic circuit that con-verts dc voltage from a solar array panel to ac voltage that can be used to power ac loads such as home appliances, lighting and power tools. However, getting the most out of such a topology requires careful analysis and the right choice of the high-side and low-side combination of an IGBT.

What solutions are available for photovoltaic inverters?

Solutions are available for single-phase and three-phase photovoltaic inverters. An entire PV inverter can be made using a single Easy 2B module. The modules incorporate an H-bridge as well as a booster and a bypass diode.

Is there a bus shoot-through in a solar inverter?

There is no possibility of bus shoot-through because IGBTs on the same leg never switch in a complementary fashion. Co-pack diodes across the low-side IGBTs can be optimized to minimize losses during freewheeling and reverse recovery. Let’s assume a 1.5-kW solar inverter is being designed with a 230-Vac output.

Can a PV inverter be made with a single Easy 2B module?

An entire PV inverter can be made using a single Easy 2B module. The modules incorporate an H-bridge as well as a booster and a bypass diode. The EasyPIM™/EasyPACK™ family has been developed in order to have a cost-effective, compact design as well as simplified and reliable mounting.

Which EF-ficiency is possible for a solar inverter design?

The latest 600-V trench IGBT is optimized for switch-ing at 20 kHz. It can be seen that this IGBT has lower total power dissipation compared to the previous-generation planar IGBT (Fig. 4). We can conclude that the highest ef-ficiency possible for a solar inverter design, a trench-gate
