5kw Hybrid Solar Inverter With Single Phase

TG series 1.5kw -6kw hybrid solar inverter with dc to ac

     Taking into account the energy consumption of the transformer in the inverter circuit using a transformer, the topology structure adopts a transformerless inverter circuit. After the DC voltage from the battery or photovoltaic array is boosted by the DC, it is then filtered by the inverter and converted into a load that can be converted into a load. Direct use of alternating current.

    Single-phase inverters generally have three structural forms: push-pull, half-bridge, and full-bridge, among which the switch in the push-pull circuit needs to withstand twice the DC voltage, it is relatively difficult to select the switch, and the use of the transformer The phase rate is low, which reduces the efficiency of the entire inverter system to a certain extent; in order to obtain the same power as the push-pull and full-bridge circuit in the half-bridge circuit, the switch tube needs to withstand twice the current. The full-bridge inverter circuit overcomes the shortcomings of the above two structures. The steady-state operating voltage of the switch tube is equal to the DC input voltage. Under the same power, the current of the switch tube is half smaller than that of the half-bridge type, so the full-bridge type is used here. Inverted structural form. The inverter main circuit consists of two parts, the DC-DC boost part and the single-phase full-bridge inverter part.
