The first control part 211 inputs a detected value of output voltage Eo, and a turn-off timing predicted value of switch Tr of the DC/DC converter 1 is calculated. The first control part 211 sends the calculation result to the switch drive signal generate part 213. The second control part 212 inputs the detected value of the output voltage and the input voltage, and it receives the turn-off timing predicted value from the first control part 211. Even more particularly, the second control part 212 calculates the peak value of the reactor current of the DC/DC converter 1 based on the turn-off timing predicted value, and it calculates the time that the reactor current decreases to a predetermined preset value from the peak value as a turn-on timing predicted value.

摘要： The control device 1A includes an on-time information generation circuit 11, a zero cross detecting circuit 12 and a PWM signal generation circuit 13. The on-time information generation circuit 11 inputs at least a power converter circuit information including an output voltage value of a power converter circuit 2, and generates the on-time information about a switch 212. The zero cross detecting circuit 12 detects a time when a inductor current becomes zero by inputting a voltage between both terminals of the inductor 214, and generates a zero cross detection signal when the inductor current became zero. The PWM signal generation circuit 13 inputs the on-time information and the zero cross detection signal, and generates a turn on signal and a turnoff signal. The zero cross detecting circuit 12 has an edge detecting circuit. The zero cross detecting circuit 12 generates a zero cross detection signal when the edge detecting circuit detected an edge appearing in a voltage between both terminals of the inductor 214. The PWM signal generation circuit 13 generates a turn-on signal when a zero cross detection signal was input. The PWM signal generation circuit 13 generates the turn-off signal, when a time based on the on-time information passed, In this way, by the present invention, a change of the inductor current is acquired precisely, and a good critical mode control is carried out.

摘要： In a control device of a power converter circuit repeating accumulation of energy to an inductor and release of energy from the inductor at each turn on/turn off timing of a switch, a zero cross detecting circuit detects a time when a current flowing through the inductor becomes zero by inputting a voltage between both terminals of the inductor directly without any resistance for detecting the inductor current. There is no electricity loss caused by the resistance for detecting the inductor current and critical mode control of the power converter circuit is precisely carried out.
