SM72295EVM provides a highly integrated gate driver solution for wide Industrial applications such as 800VA to 3kVA Pure Sine Wave Inverter , Interleaved Buck or Boost SMPS , four Switch Buck Boost SMPS etc .
This reference design is a 650-W inverter power stage designed for low-frequency (transformer based), single-phase UPS operating from a 12-V battery. The design enables low form factor and high-efficiency implementation, taking the advantage of the TI SMD MOSFET in SON5x6 package with very low RDS(ON) and low gate charge (Qg).
This reference design implements single-phase inverter (DC/AC) control using a C2000TM microcontroller (MCU). The design supports two modes of operation for the inverter: a voltage source mode using an output LC filter, and a grid connected mode with an output LCL filter.
High-Frequency Inverter Technology. The full bridge (S1...S4) generates a high-frequency square-wave signal with 40 – 50 kHz, which is transmitted via the HF transformer (Tr1). The bridge rectifiers (D1...D4) convert the square-wave signal back to DC voltage and store it in the intermediate circuit (L1+C2).
• Inverter Single Phase [M2] – DC-AC macro accepts a DC voltage and uses a full bridge single phase inverter to generate a sine wave. The output filter, filters high frequencies, therefore, generating a smooth sine wave at the output. • Sepic DC-DC with MPPT Battery Charging [M3] – DC-DC macro accepts DC input from the PV
