Abstract: PURPOSE: To eliminate an ataxia phenomenon by changing an operating point into either one of current source characteristic area or voltage source characteristic area when output consumption is less than a maximum output. CONSTITUTION: Means 11 and 12 are provided for sampling and measuring a voltage V and a current I supplied from a current generator 1 to a converter 2. A threshold detector 3 supplies a logic signal C expressing the ataxia state or non-ataxia state of the converter 2 corresponding to a related threshold value. Each time the converter 2 tries to start the ataxia state, in other words, the operating point of a controller intersects (crosses) a maximum power point Pmax on output current/voltage characteristics I(V) of the current generator 1, the parameter of the current I or the voltage V at the operating point gets lower than a threshold Imax or Vmin and the state of an inverter 42 is inverted as a result.  Thus, the polarity of a deviation signal ε in a control loop circuit 4 is inverted, the operating point of the converter 2 is turned toward the maximum output point Pmax , and the generation of ataxia at the converter 2 is prevented.
