Title: Temp. independent control cct. for inverters - has operational amplifier square wave output controlling capacitors alternate polarity charging
Inventor: HAHN KARL DIPL-ING
IPC: H02M7/525
Filed: 1973-10-09
Abstract: The temperature independent control circuit for inverters has an operational amplifier whose square wave output is used to control the inverter. The output is connected over a feedback resistor to the non-inverting input and over two oppositely poled diodes separately to two full-wave rectifier diodes that alternately charge a capacitor coupled to a voltage divider. The capacitor is connected at one electrode over a matching resistor to the amplifier non-inverting input, and at its other electrode to the rectifier diodes, and directly to the amplifier inverting input. Tha capacitor is charged alternately over the two diodes and its polarity reversals cause the amplifier output to change state, which in turn reverses the capacitor charge polarity.
