Claims

[Scope of utility model registration request]

a power control unit provided with a plurality of semiconductor control switches that control each phase current of the alternator by inputting a trigger signal; and a fixed load to which the output of the generator is supplied via the power control unit. , a gate signal generation unit that detects the zero-crossing point of each phase current and outputs a plurality of gate signals for setting the trigger period of each of the switches; and a gate signal generator that compares the output of the generator with a set output and generates each of the trigger signals. an adjustment signal generation unit that outputs adjustment signals for adjusting the respective output timings; and an adjustment signal generation unit that receives the respective gate signals and the adjustment signals and outputs each of the trigger signals to control the output of the generator to the set power. A generator testing device equipped with a trigger signal generator.
