For current waveforms with a small peak-to-peak to average ratio, the difference will be less and the simpler average current calculation may be sufficient.
この図は、アクティブPFC回路による電流波形の改善のイメージです。
The diagram below is a conceptual illustration of improvement of a current waveform by an active type PFC circuit.
Short-circuit current waveform in fast-pull-down circuit. The source current reverses as circuit capacitances recharge the input capacitance to cause a slight positive overshoot at the +12V input.
Because the power is an alternating current waveform and impedance can vary as a function of frequency, it is necessary to state what frequency the 0 dBm standard is based upon.
Since IDS followsinductor current for the"on" cycle(Figure 2), the current waveform ramps up, resulting in greater switching loss during the turn-off edge compared to the turn-on edge.
As with the MOSFET conduction loss calculation earlier in this article,integrating the square of the inductor current waveform provides a more accurate result.
The fast gate pull-down circuit of Figure 2 may not decrease the initial short circuit current,but the PNP Darlington pull-down will quickly terminate the current waveform.
The waveform diagram shows a standard example in which LX is the voltage waveform at the switching node,IONH and IONL are the current waveforms that accompany switching, and IL is the inductor current..
Detail of a typical step-down MOSFET current waveform for the purpose of accurately estimating MOSFET conduction losses. The following equation more accurately predicts losses for a ramped waveform by replacing the simple I2 term with the integral of I2 between IP and IV.
Ii Discharge the remaining electric charge in the circuit's capacitor and measure the current waveform. If there is a component like a thermistor with a resistance that changes depending on the temperature,measure the current waveform at the minimum resistance.
In this state, the nonsynchronous type using a diode, because it can cause a current to flow only in one direction, the current entering the negative region, indicated by an orange-color waveform,disappears, and the current waveform assumes a stop-and-go state with zero periods.
The gain and phase predicted by the above model differ from that observed in practice because of the"sample andhold" effect in the PWM comparator that results from the current waveform getting sampled only once every cycle.
