The working principle of the DC to AC inverter

2022-02-28

Inverter is a DC to AC transformer. In fact, it is a process of voltage inversion with converter. The inverter converts the AC voltage of the power grid into a stable 12V DC output, while the inverter converts the 12V DC voltage output by the adapter into high-frequency high-voltage AC; Both parts also use the more widely used pulse width modulation (PWM) technology. Its core part is a PWM integrated controller, the adapter uses UC3842, and the inverter uses tl5001 chip. The working voltage range of tl5001 is 3.6 ~ 40V. It is internally equipped with an error amplifier, a regulator, oscillator, PWM generator with dead band control, low-voltage protection circuit and short-circuit protection circuit.(inverter)
