Filed: 1981-12-07
Abstract: PURPOSE:To ensure a safe start up and operation of a current type inverter in response to a load within the frequency range allowed by the main circuit of the inverter, by detecting the resonance frequency of the load tank circuit and setting the  thus detected resonance frequency automatically as the inverter operation frequency. CONSTITUTION:The oscillation voltage of a tank circuit is detected by an instrument transformer PT, and is converted into a rectangular wave by a zero-cross comparator CP0, so that a series of pulses corresponding to the period of operation of the  tank circuit is obtained. The trailing edge of the output from the comparator CP0 is detected by a differentiation circuit DEF. An R-S type flip-flop FF1 is set by the  output from a start pulse generating circuit MM and is reset by the output from the  differentiation circuit, so that an output Q of a logical level ''1'' is obtained only  within the period corresponding to the later half of operation cycle of the tank circuit.  A counter C, the gate of which is opened only during outputting of the output Q,  counts the number of pulses produced by a reference pulse generator CK and stores  the counted number which corresponds to the resonance frequency of the tank circuit.  The counted value is then inputted to a D/A converter the output of which is delivered  to a voltage-frequency converter VF which produces a frequency signal for the operation of the inverter.
