When system is locked without starting, so with intermediate voltage on T1 gate (so ok to me) -> a bit oscillation from the USB switching supply is amplified and reversed on T1 drain -> reversed again is present somehow amplified on Q3 drain -> almost completely cut off on D3 cathode (...
The invention discloses a current-loop communication loop-based power supply control circuit. One end of a voltage-dividing resistor R1 and the anode of a diode D1 are connected to a high-level loop S of a current ring communication loop; the cathode of the diode D1 is connected to the...
This invention relates to an electric current loop control method and system for power supply device. To overcome the conflict between holding stability and increasing gain, based on traditional single current regulator, this invention adds a filter to filter the transient voltage sample, a subtract...

The dc-link voltage controller is designed for balancing the power flow in the system. The third loop is the grid current control loop which regulates the grid current. The grid current loop has the responsibility of power quality issues and current protection; thus, harmonic compensation and ...
The power supply can be 220V alternating current power supply or direct current power supply of rechargeable accumulators. 电源可以是220V交流电源或可充电蓄电池直流电源; ip.com 6. At present, iontophoresis apparatus is a method that direct current power supply, or pulse electric current power supply...
the external current loop was used to regulate the output current.Two advance-delay compensation nets were devised for every loop.A UC3875 chip operating at 25 kHz was used to manage the power supply.Theoretical analysis was conducted,and experimental results are shown for the power supply. ...
Most power supply regulators either cause the output voltage to drop- off gradually, or caused output oscillation upon reaching or exceeding the limit current. Current limit feedback to an error amplifier within a switching regulator is used to control the output voltage, prevent oscillation, insure...
