Abstract
An apparatus for generating high voltage (HV) driving signals associated with an ion mobility detector comprises a ground-based HV base module and a HV deck module coupled by an interconnect module. The HV base module implements dual power supplies that together drive a drift tube voltage signal to the high-voltage-based deck module. Each of the power supplies is regulated by a combination open loop and closed loop controller. The HV deck module implements one or more grid modules that generate a bipolar voltage that floats on the drift tube voltage signal. Also included may be a pulse generator configured to generate at least one synchronizing timing pulse. Power supplies within the apparatus may be synchronized based on the synchronization timing pulse.
