ABSTRACT:
A method for controlling current converter valves of a load-guided parallel oscillator inverter of an induction furnace includes supplying the inverter from a direct current source having positive and negative poles, and adjusting a current flow from the direct current source across the parallel oscillator by firing two diagonally opposed current converter valves of the inverter at a time. The method of the invention includes firing the two diagonally opposed current converter valves at a time with a delay between them for intermittently producing a short circuit current from the positive pole of the direct current source to the negative pole of the direct current source through two of the current converter valves being directly series-connected.
