Suspended pulse multi-arm-bridge driver provided with constant-current diodes for dividing voltage

The invention discloses a suspended pulse multi-arm-bridge driver provided with constant-current diodes for dividing a voltage. The suspended pulse multi-arm-bridge driver provided with the constant-current diodes for dividing the voltage consists of M arm bridges, wherein the M arm bridges include an arm bridge 1, an arm bridge 2, . . ., an arm bridge j, . . ., and an arm bridge m in sequence, namely, M={2, . . ., j, . . ., m}; m is greater than or equal to 2; any arm bridge j is constructed by sequentially connecting two suspended pulse driving modules and N constant-current modules in series; a head end and a tail end of the arm bridge j are connected with a positive end HV+ and a negative end HV- of a direct-current power supply respectively; and the two suspended pulse driving modules refer to a suspended pulse driving module H and a suspended pulse driving module L respectively. The suspended pulse multi-arm-bridge driver has the advantages of simple design, reasonable structure, convenience in construction and high universality. Through adoption of the suspended pulse multi-arm-bridge driver, the defect of poor high-voltage adaptability of an existing pulse driver can be overcome, and conversion of a suspension level can be realized effectively.
