Hybrid Solar Inverter With Mppt Controller

TG series pure sine wave hybrid solar inverter with mppt comntroller

    The working principle of the inverter is through the turn-on and turn-off of power semiconductor switching devices. The basic circuit of a single-phase inverter that converts DC power into AC power has a network. There are three types of promotion: half-bridge type and full-bridge type. Although the circuit structure is different, the working principle is similar. Semiconductor devices with switching characteristics are used in circuits. The control circuit periodically sends switching pulse control signals to the power devices to control each power device to be turned on and off in turn, and then boost or step down through the transformer coupling. The main line filter output meets the requirements of AC.

    Input interface part:

   The input part has 3 signals, 12V DC input VIN, work enable voltage ENB and Panel current control signal DIM. VIN is provided by Adapter, ENB voltage is provided by MCU on the main board, its value is 0 or 3V, when ENB=0, the Inverter does not work, and when ENB=3V, the Inverter is in normal working state; and the DIM voltage is provided by the mainboard, The variation range is between 0 and 5V. When different DIM values are fed back to the feedback terminal of the PWM controller, the current provided by the Inverter to the load will also be different. The smaller the DIM value, the greater the current output by the Inverter.
