1, phase voltage regulator type    
Surge-type phase shift by changing the size of the conduction angle to adjust the output voltage, which trigger good continuity, stable output voltage, no voltage surge, can limit the instantaneous current, suitable for all types of loads, current transformers, inductors variable resistive load coils and are using this trigger. However, this would trigger the grid harmonic interference.
2, divided by zero-power adjustment type    
Divided by zero-tone sine wave power type is zero trigger to complete sine wave as a unit, by changing the on-off cycle of the sine wave to adjust the output power. So that conduction of the uniform distribution of the sine wave, voltmeter, ammeter hands only slight jitter, running more than one regulator to avoid concentration of current, because the zero point of the sine wave is triggered on the grid so no pollution, high power factor, but can not instantaneous current limit, so the tube furnace can not be used for inductive loads and variable resistive load, constant resistive load generally use this trigger. Meter output cycle setting must be consistent with PWM input period panel, otherwise it will produce erroneous calculations.
3, will be zero-cycle power adjustment type    
Given period zero-type instrument output power adjustment period setting must be consistent with PWM input period panel, otherwise it will produce erroneous calculations. PWM (fixed week period) mode Output: means within a fixed number of time to change the on-off ratio, and power level adjustments made on the way.
