a phase is different over a wide range in a high-frequency power-supply apparatus in which high-frequency power which is always in a resonance state by controlling an inverter is supplied to a load comprising an LCR series resonance circuit in a high-frequency circuit such as a tank circuit...
resulting in a very low spike current during latch up and improved paralleling turn on. The capacitance between the gate and the first electrode may be increased, which may reduce the Q factor of LCR series circuit during paralleling turn off. Hence the turn-off oscillation problem may be impr...
Cpis the capacitance, in farads, as measured using a parallel circuit model. Rp— Rpis the resistance, in ohms, as measured using a parallel circuit model. D— Dis the dissipation factor of the circuit. The dimensionless dissipation factor is directly proportional to how quickly an o...
