The direct current conversion circuit is composed of an MOS switch tube and an energy storage inductor, and input pulses are amplified by a push-pull amplifier and then drive the MOS switch tube to perform switching action, so that the inductor is charged and discharged by direct current voltage, and the other end of the inductor can obtain alternating current voltage.

The portable multifunctional inverter system is mainly composed of switching elements such as transistors, and the switching elements are regularly switched ON and OFF repeatedly (ON and OFF), so that direct current input is changed into alternating current output. Of course, such an inverter output waveform generated purely by the open and closed loops is not practical. Generally, it is necessary to form a pulse waveform train (pseudo-sine wave) by narrowing the voltage width near both ends of a sine wave and widening the voltage width at the center of the sine wave and by operating a switching element in one direction at a constant frequency in a half period by using a high frequency pulse width modulation (SPWM). The pulse wave is then passed through a simple filter to form a sine wave.
