摘要： This invention provides a power supply device which widens a narrow output control width which is a drawback of a conventional voltage resonant power supply, and in adopting as a switching control element a low-cost IGBT (Insulated Gate Bipolar Transistor) which permits a large current, optimizes a gate signal waveform to minimize a switching loss in control because the IGBT has a larger loss than an FET. A voltage resonant converter includes a switching IGBT (201) connected to a power supply, a first resonant capacitor (204) series-connected to the IGBT (201), an IGBT (202) series-connected to the first resonant capacitor (204), an exciting coil (18) connected between the power supply and a node between the first resonant capacitor (204) and the IGBT (202), a second resonant capacitor (205) parallel-connected to the IGBT (202), and regenerative diodes (206, 207) respectively parallel-connected to the IGBTs (201, 202). A gate control signal to the IGBTs (201, 202) allows generating a switching timing signal by waveform shaping from a transmission voltage (3) of an insulated driving transformer to ensure reliable switching operation.
