12-volt car inverter in the use of how old break?
How the inverter works:
? 1. DC can be converted into alternating current through the oscillation circuit
????2. The resulting alternating current is then boosted by the coil. At this time, the alternating current of the square wave is obtained
????3. Rectify the resulting alternating current to get a sine wave
??????AC-DC is relatively simple, we know that the diode has a one-way conductivity, you can use this characteristic of the diode connected into a bridge, so that one end is always inflow, the other end is always out of this to get the voltage sinusoidal change Of the DC. If you need smooth DC also need to rectify, the simple way is to connect a capacitor.
??????Inverter is a DC to AC transformer, in fact, it is a voltage inverter with the process. Adapter is the utility power grid AC voltage into a stable 12V DC output, and Inverter is the Adapter output 12V DC voltage into high-frequency high-voltage alternating current, the two parts are also used with the current more Pulse width modulation,
??PWM technology. Its core part is a PWM integrated controller, Adapter with the UC3842, nverter is used TL5001 chip. TL5001 operating voltage range of 3.6 40V , which has an internal error amplifier, a regulator, oscillator, a dead zone control of the PWM generator, low voltage protection circuit and short circuit protection circuit.
??????Inverter, can be classified from the output waveform, power, engineering structure.
?????From the waveform on the points: one is a square wave inverter, the other is a sine wave inverter.
?????From the power up to divide, can be high power and low power two categories. Less than 5000W can be called low-power, more than 5000W called high-power inverter.
