摘要：A smart buck conversion device with a long service life, comprising a high-frequency modulation unit (30), a filter inductor filter unit (50), and an inverter unit (60). The high-frequency modulation unit comprises a first switch transistor (Q7) and a second
switch transistor (Q10); a drain of the first switch transistor is used for connecting to a direct current voltage; a source of the first switch transistor is connected to a drain of the second switch transistor; a source of the second switch transistor is grounded; a gate of the first switch transistor and a gate of the second switch transistor are respectively connected to two PWM pulse signals (PWM1, PWM2)having opposite phases. The filter inductor filter unit comprises a filter inductor (L3); a front end of the filter inductor is connected to the source of the first switch transistor; an input end of the inverter unit is connected to a rear end of the filter inductor; the inverter unit is used for inverting and converting a half-wave pulsating voltage output from the rear end of the filter inductor into a sine alternating current voltage. The smart buck conversion device does not need an electrolytic capacitor, can prolong the service life, is easy to carry, and can avoid the interference on a power grid.
