The system is running at less than optimal gain state, so light load conversion efficiency at light load conditions will also fall

The maximum inductance to satisfy this condition can be obtained from the following equation: When the drive circuit 600 volt fluorescent light, the efficiency curve of a multilayer PZT has a push-pull topology. When the input voltage is low, the conversion efficiency is higher than 85%; at high input voltage, the conversion efficiency decreases with the decrease in gain of PZT. Magnetic and  circuit breakers , the linear approach to reducing the fluorescent lamp dimming to reduce work efficiency. In the magnetic circuit of the transformer, the loss due to the circulating current in the resonant circuit with the generated electric current  mcb circuit breaker  the fluorescent lamp and maintain independent constant, the decrease in the conversion efficiency at light loads. In PZT circuit, since the system is running under light load conditions below the optimum gain state, the light load  Voltage stabilizer  efficiency will fall. Light load efficiency of these two circuits can be improved using pulse dimming technology. This method can visually sensed higher than the frequency modulation of the duty cycle by on / off control the average current of the fluorescent lamp, the fluorescent lamp working at full load current.
