Title:
共振インバータ
Document Type and Number:
Japanese Patent JP6756286
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a resonance inverter capable of suppressing generation of a ripple current of a smoothing capacitor and driving a main switch at a resonance frequency.SOLUTION: The resonance inverter includes: a push-pull circuit 11, a resonance tank circuit 12 and a controller 5. The controller 5 calculates a difference current ΔI expressed by the following formula: ΔI=(I-I)-(I-I), using a center ON-state current I, a switch ON-state current I, a center OFF-state Iand a switch OFF-state current I. Using the difference current ΔI, a driving frequency f of switches 3, 4 is controlled.SELECTED DRAWING: Figure 1
