摘要： A bridge circuit, intended for use as a PWM driver of an inductive load, includes at least one source driver transistor connected in series totem-pole fashion with a sink driver transistor. A base resistor is connected from base to emitter of one of the driver transistors. This totem pole circuit is connected across a pair of DC supply conductors. A protective fly-back diode is connected across the one driver transistor. An auxiliary resistor is connected from the base of the auxiliary transistor to the emitter of the one driver transistor. When a fly-back diode across the one driver transistor conducts, the one driver transistor tends to conduct in the reverse direction and to store charge that in a subsequent period leads to shoot-through currents through the source and sink drivers. The auxiliary transistor turns on only when the fly-back diode conducts and shunts the base-collector of the source transistor, preventing its turning on and storing charge, and thus preventing potentially damaging shoot-through current through the driver transistors. The added auxiliary components do not cause additional power being drawn from the supply source, and therefore do not cause additional heating in the integrated circuit in which the bridge circuit may be formed. A pair of such half wave totem pole circuits may be paralleled to form a full wave bridge.
摘要翻译：旨在用作感性负载的PWM驱动器的桥接电路包括至少一个源极驱动器晶体管，其以串联方式串联连接到宿驱动晶体管。一个基极电阻从一个驱动晶体管的基极耦合到发射极。该图腾柱电路连接在一对直流电源导体上。一个驱动晶体管两端连接一个保护性反激式二极管。辅助电阻从辅助晶体管的基极连接到一个驱动晶体管的发射极。当一个驱动晶体管上的反激二极管导通时，一个驱动晶体管倾向于反向导通，并且存储电荷，在随后的时间段内导致穿过源极和漏极驱动器的直通电流。只有当回扫二极管导通和分流源极晶体管的基极集电极时，辅助晶体管导通，防止其导通并存储电荷，从而防止通过驱动晶体管的潜在损坏的直通电流。添加的辅助部件不会从供应源引起额外的电力，因此不会在可形成桥接电路的集成电路中引起额外的加热。一对这样的半波图腾柱电路可以并联以形成全波桥。
