共振インバータ
Document Type and Number:
Japanese Patent JP6756285
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a resonance inverter capable of suppressing generation of ripple currents of a smoothing capacitor and efficiently resonating an output current.SOLUTION: A push-pull circuit 11 includes a resonance tank circuit 12 having a first auxiliary switch 4a, a second auxiliary switch 4b and an auxiliary capacitor C, and a controller 5. The controller 5 switches between a first period Tfor concurrently turning on a first main switch 3a and the second auxiliary switch 4b and a second period Tfor concurrently turning on a second main switch 3b and the first auxiliary switch 4a. Thus, an output current Iis resonated. The controller 5 switches between the first period Tand the second period Twhen a difference ΔI between a first current Irunning through a first coil part 21a and a second current Irunning through a second coil part 21 is not more than a predetermined value I.SELECTED DRAWING: Figure 1
