ELECTRICAL INVERTER CIRCUIT ARRANGEMENTS

摘要

A transistor inverter circuit comprises two transistors which are switched on alternately via respective control circuits. Each control circuit provides a direct path for a TURN OFF pulse but incorporates in the turn on path a silicon controlled rectifier associated with a time delay circuit which delays the switching on of the silicon controlled rectifier after occurrence of the TURN ON pulse. Thus, each transistor receives a TURN OFF pulse immediately but the other transistor does not receive the TURN ON pulse until a time delay has lapsed. The time delay is sufficient to ensure that each transistor is fully switched off before the other is turned on.
