VIBRATION CIRCUIT INVENTOR AND METHOD OF APPLICATION OF SUCH INVENTOR

摘要

1. Inverter (20) of the oscillating circuit with a rectifier, an intermediate circuit (202) of direct current and an inverter (203), which contains a controlled switch, and the output of which forms the output of the inverter of the oscillatory circuit, and through which current is supplied to the connected load, and the inverter (20) of the oscillating circuit has a first regulating device, (10), with which the operating point (A) of the inverter (20) of the oscillating circuit is regulated, which is determined by the phase angle between the output current (I) and the voltage (U) at the output of the inverter (20) of the oscillating circuit, for which the first regulating device (10) determines as a control action the frequency of the output current (I), regulated by the inverter (203), and the inverter (20) of the oscillating circuit has one phase detector (8), with which, depending on the point of passage of the output current I through the zero value, the actual value of the phase angle is determined, and the inverter of the oscillatory circuit has a device for determining the point of passage of the output current (I) through a zero value, characterized in that to determine the actual value of the phase angle, the difference (T-T) of the measured time value (T) is determined, which is measured between the time when on the control electrode of the controlled switch of the inverter, through which the output current (I) flows, was sent a turning on pulse, and the moment in time when the output current (I) took zero value and the known time (T) lag between the moment when the inverter terminal (203) designed to receive the output current I by means of a
