| description | To provide a resonance type power conversion circuit and the like that mitigate calculation costs greatly with a simple configuration.SOLUTION: A resonance type power conversion circuit comprises: a resonance circuit that includes a first LC resonance circuit and a switching element and outputs output voltage or output current to a load; a detection circuit for detecting output information that is the output voltage or output current; a calculation control unit that, on the basis of the detected output information, searches for a maximum point in the output information's characteristic with respect to operation frequencies and determines an operation frequency corresponding to the maximum point obtained by the search; and a signal generation unit that generates a drive control signal having the determined operation frequency and performs frequency control on the switching element on the basis of the drive control signal. The resonance circuit has the output information's characteristic with respect to operation frequencies that has a load independent point that corresponds to the maximum point and is independent of the load, feeds back the drive control signal including the output information to the switching element, and is driven at the load independent point by frequency control using the drive control signal.SELECTED DRAWING: Figure 1
【課題】簡単な構成で、演算コストを大幅に軽減する共振型電力変換回路等を提供する。【解決手段】本発明の共振型電力変換回路は、第１のＬＣ共振回路とスイッチング素子を含み、出力電圧又は出力電流を負荷に出力する共振回路と、出力電圧又は出力電流である出力情報を検出する検出回路と、検出された出力情報に基づいて、動作周波数に対する出力情報の特性における極大点を探索して、探索された極大点に対応する動作周波数を決定する演算制御部と、決定された動作周波数を有する駆動制御信号を発生して、駆動制御信号に基づいてスイッチング素子を周波数制御する信号発生部とを備える。共振回路は、極大点に対応する、負荷に依存しない負荷非依存点を有する動作周波数に対する出力情報の特性を有し、出力情報を含む駆動制御信号をスイッチング素子に帰還させ、駆動制御信号による周波数制御により前記負荷非依存点で駆動する。【選択図】図１ |
