Shunt Regulator
A shunt regulator is included in the power supply section of the Tambourine 100. The shunt
regulator is a switching type, wherein dissipative elements (power resistors) are switched
across the DC bus, whenever the voltage reaches a predetermined level. The function of the
shunt regulator is to regulate the voltage of the DC bus during the period of motor
deceleration, when there is a net energy outflow from the motor to the servo drive, to prevent
the servo drive from disabling itself as a result of an “over-voltage" type reason.
When the capacitors charge-up reaches the predetermined shunt threshold level, the shunt
regulator begins its regulating action. The bus is regulated to the specific model type voltage,
until the regeneration-energy is dissipated.
