SYSTEM AND METHOD FOR PROVIDING MULTIPLE SIMMER OUTPUTS

摘要

A power supply and circuitry system for powering HVPT devices includes a power supply circuit that selectively provides an operating power and a simmer power to multiple HVPT devices. The system also includes a trigger circuit for each respective HVPT device that selectively couples the power supply circuit to one HVPT device to provide the operating power thereto. The system also includes a simmer control circuit for selectively coupling the power supply circuit to the HVPT devices to provide the simmer power thereto, the simmer control circuit further including a simmer switch circuit for each HVPT device, wherein each simmer switch circuit comprises an input coupled to the power supply circuit to receive the simmer power therefrom and an output coupled to one HVPT device. The simmer control circuit also further includes a simmer drive circuit coupled to each simmer switch circuit for selectively enabling the simmer switch circuits.

1. A power supply and circuitry system for powering multiple high-voltage-pulse-triggered (HVPT) devices, the system comprising:
a power supply circuit configured to selectively provide an operating power and a simmer power to at least two HVPT devices; a trigger circuit for each HVPT device of the at least two HVPT devices that selectively couples the power supply circuit to one HVPT device of the at least two HVPT devices to provide the operating power thereto, wherein each trigger circuit is coupled to one HVPT device of the at least two HVPT devices; and a simmer control circuit for selectively coupling the power supply circuit to the at least two HVPT devices to provide the simmer power thereto, the simmer control circuit comprising:
a simmer switch circuit for each HVPT device of the at least two HVPT devices, wherein each simmer switch circuit comprises an input coupled to the power supply circuit to receive the simmer power therefrom and an output coupled to one HVPT device of the at least two HVPT devices; anda simmer drive circuit coupled to each simmer switch circuit for selectively enabling the simmer switch circuits.
