Solid-state high voltage switch and switching power supply

摘要: A switching circuit (50) comprising cascaded transistor stages (52a, 52b, ...52n and 54), connected between a high voltage terminal (62) sense resistor (RS) coupled to low (64). The stage (54) closest the is referred as current gain (54), all other ...52n) are component ...52n). Blocking diodes (DD) across forming continuous path When an enable signal provided 54) sequentially enter conduction, beginning with proceeding through As each enters resulting drop will cause corresponding blocking diode avalanche, allowing flow. Eventually, of turned on, creating conductive completing (50).
