A High-Frequency Discharge Module with Power Feedback for the Pumping Systems of Solid-State Lasers

“…Since the operating principle of a high-frequency discharge module does not change upon a switch from current feedback to power feedback, the behavior of the temporal dependences of the current in the inductor, along with that of the voltage across the capacitor, is also constant [1].…”

“…In order to describe quantitatively the processes in our discharge module of interest, let us use the approach we developed when analyzing a circuit with current feedback [1]. The calculations performed for these circuits differ in that, in the discharge module with power feedback, an arbitrarily shaped meanpower pulse, rather than a current pulse, is formed in the lamp.…”

“…A circuit of a high-frequency discharge module with current feedback and having a number of advantages over the existing circuits for pumping flash lamps was considered in [1].…”

“…A circuit for controlling the power-regulating switch and maintaining the relative value of power pulsations in the lamp at a constant level is proposed. 300 280 260 240 220 200 180 160 140 120 100 80 60 40 20 0 1 2 3 4 5 6 7 8 9 10 Lamp 160 150 140 130 120 110 100 90 80 70 60 50 40 30 20 10 0 Power, kW circuit of a discharge module with current feedback [1]. The change observed in the operating conditions clearly reduces the pumping efficiency and complicates pump-energy stabilization.…”

“…2) does not differ at all from the power circuit of a discharge module with current feedback [1]; it does, however, have a different control circuit.…”
