摘要 |
Three or more circuits including a driving inverter circuit (A1) and rectifier circuits (A2-A4) are connected in series, each of the circuits including a high-voltage side MOSFET and a low-voltage side MOSFET connected in series as well as a smoothing capacitor (Cs1-Cs4) having positive and negative terminals between which the MOSFETs are connected. LC series circuits (LC12, LC13, LC14), each including a capacitor (Cr) and an inductor (Lr), are disposed individually between one specific circuit (A1) and the other circuits (A2-A4) with periods of resonance of the LC series circuits (LC12, LC13, LC14) made equal to one another. In performing DC/DC power conversion through charging and discharging operation of the capacitors (Cr), a resonance phenomenon of the LC series circuits (LC12, LC13, LC14) is used to improve conversion efficiency and achieve a reduction in size of the apparatus structure.
