Inverter is a DC to AC inverter, which is actually a voltage inversion process with the converter. The converter 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 power; Both parts also use the widely used pulse width modulation (PWM) technology. The core part is a PWM integrated controller, with UC3842 used as the adapter and TL5001 chip used as the inverter. The working voltage range of TL5001 is 3.6-40V, and it is equipped with an error amplifier, a regulator, an oscillator, a PWM generator with dead zone control, a low-voltage protection circuit, and a short-circuit protection circuit.
Simply put, an inverter is an electronic device that converts low voltage (12 or 24 volts or 48 volts) direct current into 220 volts alternating current. Because it is usually used to rectify 220V AC power into DC power, and the function of inverters is the opposite, hence the name. In the era of 'mobile', mobile office, mobile communication, mobile leisure and entertainment. In the mobile state, not only does it require low-voltage DC power supplied by batteries or accumulators, but it also requires the indispensable 220V AC power in daily environments, which can be met by inverters.
Job characteristics
1.High conversion efficiency and fast startup;
2.Good safety performance: The product has five protection functions: short circuit, overload, over/under voltage, and over temperature;
3.Good physical performance: The product adopts an all aluminum shell with good heat dissipation performance, surface hard oxidation treatment, good friction resistance, and can withstand certain external forces such as compression or impact;
4.Strong load adaptability and stability.
Work efficiency
The inverter itself consumes a portion of electricity during operation, therefore, its input power must be greater than its output power. The efficiency of an inverter is the ratio of the output power to the input power, that is, the efficiency of an inverter is the ratio of the output power to the input power. If an inverter inputs 100 watts of DC power and outputs 90 watts of AC power, then its efficiency is 90%.
