TH21715EX - Phase-controlled power modulation system - Google Patents

Abstract

The phase-controlled power modulation system shuts the switch in response to the condition of the electrical circuit threat, thereby eliminating the need for an outage.Normal operation is in the reverse phase control module. Reverse (RPC) When the inductive load sensing machine detects the presence of the inductive load, the system switches to the forward phase-controlled module (FPC) to reduce the spike of the induction load. The voltage that will produce different effects from the load resistance to the voltage change interval. When the overcurrent sensing device detects an overcurrent, the system switches the switch into the asymmetric hybrid waveform (AFCP) module to deliver maximum power while still Remain in the power of the switch electric current control In the AC MODE, the RPC component of the half-cycle waveform is cut off at the current limit, while the FPC component of the same rated half-cycle waveform is ignited after. The source voltage is lowered to an apparent switching threshold below the current limit to insure that the current limit will not be deflected again during the same half cycle. In response to the extreme temperatures, the modulus of the end transition is passed through to reduce the heat generated at the switch until the temperature drops.
