GENERATOR OF DRIVE SIGNALS FOR TRANSISTORS CONNECTED IN A HALF-BRIDGE CONFIGURATION

摘要

The generator of drive signals comprises a ramp generator (11) suitable for receiving a square waveform input signal and for converting it into an output signal variable between a lower level and an upper level with upward and downward ramps having a preset slope, a first comparator (21) with a non-inverting input connected to the output of said ramp generator (11) and an inverting input connected to a first reference signal source (23) and a second comparator (22) with an inverting input connected to the output of said ramp generator (11) and a non-inverting input connected to a second reference signal source (24).
