More and more people have cars now, it seems that we can say when you own a car you can start your unhampered life. However, you may not feel as comfortable as you are at home or office because the lack of the electricity.
When you schedule an appointment with a client, you left the office and a little while later
kids to go out for fun,and he complian at the back seat that why he can not play the game
they do without light at the evening? With WELLSEE portable car inverter, you do not

inverter circuit
Full-bridge inverter circuit has overcome the shortcomings of push-pull circuit. The power transistors adjust the output pulse width, and then the output AC Voltage RMS is Changed. Since this circuit hasnot distort. The disadvantage of this circuit is that the up and down legs power transistors is not a tota continued current loop, even though connected to the inductive load, the output voltage wave form will l land. That’s why it must have special driver circuit, and by isolated power supply. Furthermore, in order to prevent the upper and lower leg joint conduction occurs, it must be designed as turning off the circuit before bringing up it, that is setting dead time. The circuit structure is complicate.
Push-pull circuit and Full-bridge both need step-up transformer in the output. Due to step-up transformers are bulky, inefficient and expensive, with the developing of the power electronics and microelectronics technology, using high-frequency step-up transform to achieve inverter. It can achieve high power density inverter. This inverter circuit uses push-pull circuit structure in the first stage step-up circuit, but the frequency is above 20KHz. Step-up transformer uses high frequency core material. It is in small volume and light weight. After high frequenct, and through high-frequency transformer, it is changed into high-frequency AC current. And then by the high-frequency rectifier circuit, we will get high voltage DC (generally above the 300W).It finishes inverter through the frequency inverter circuit. It will improve the inverter power efficiency very much to use this circuit structure. And at the same time, the no-load loss is correspondingly reduced, the efficiency improved. The disadvantage of the circuit is the complexity circuit, lower reliability than the above two circuits.
