solar pure sine wave inverter 2000w

  Since the self-excited push-pull converter cannot meet the requirements of output voltage stability, it has been widely used. #off grid dc to ac inverter          The so-called "excited" means that the oscillation work of the circuit is realized by the excitation of the external control signal. Figure 2 (a) shows the circuit schematic diagram of its exciting push-pull DC converter. It can be seen from the figure that the base feedback winding of the previous self-excited push-pull converter has been cancelled, and the link that replaces its function is the power control component IC. #2kw inverter manufacturers             In the early days, TDA1060 was used, and LM3842 or LM3845 were used later. . #pure sine wave inverter charger 1000w                      The power control component IC is used to send a square wave control pulse to make the UPS work. At the output of the transformer, a feedback signal proportional to the output voltage is sent back to the IC, so that it can adjust the control pulse according to the change of the input voltage and the change of the output load. Width to ensure that the output voltage is stable within the design range.
