Abstract
A resonant power conversion device includes: a main circuit provided with a semiconductor switch, a capacitor and an inductor connected in series or parallel to the semiconductor switch; and a drive circuit configured to drive the switching element. The switching element enters an off-state or an on-state depending on a control voltage input to a gate terminal, and the drive circuit includes two or more types of control voltages, as a control voltage at which the switching element enters an off-state.
Claims10
A resonant power conversion device comprising:
- a main circuit provided with a switching element having a high-potential terminal, a low-potential terminal and a control terminal, and provided with a capacitor and an inductor connected in series or parallel to the high potential terminal or the low potential terminal, and the main circuit being configured to convert and output input power;
- and
- a drive circuit configured to output a control signal to the control terminal and drive the switching element, wherein
- the switching element enters an off-state or an on-state depending on a signal value of the control signal input to the control terminal,
- the drive circuit includes two or more types of signal values, as the signal value of the control signal at which the switching element enters an off-state, and
- each of the two or more types of signal values is set in accordance with a resonant frequency to be generated in the main circuit.
