1KW PFC Circuit UC3855 for its function requires a dc supply voltage of 10 to 20V . His sampling is during normal operation of 17 to 25 ma. The integrated circuit additionally contains the input VCC zener diode of 20V. The maximum current for this diode is, however, only 20 mA [19]. Therefore, it is…
TAS5706A Class D Amplifier was itself the signal processor. From this parts depend all the other elements. Has an impact on the type of power supply, the control method of the type converter. That is why he was first selected DSP processor. There are more firms that produce the processed signal processors whose internal connection…
Adjustable Laboratory Power Supply SMPS design a lab power supply switching concept, which will work in kvazirezonancním fashion. The source should have one symmetrical output 0 to ±30 V / 5A (UCC28600) and one output single-ended +5V / 2A. (TOP243) Equipment opatrete digital indication of the output voltage and current and the electronic protection during…
High-frequency RF Power Amplifier is a device that is able to change (amplify) the amplitude of the input signal using power supplied from the power supply. This energy is transformed into the amplified output signal and partly on the heat (the amount of the dissipated power radiated as heat is dependent on the efficiency of…
HIP4081A two-channel output stage amplifier working in class D power 2×100 W to the load 8 Ω. For its construction are used mostly SMD components to the parasitic characteristics of the conductive connections shown what at least. The end-amplifier working in class D was designed in the “non-integrated” version in engagement with each of the…
UC2525 Designed smps switching power supply contains corrector pfc power factor and switching push-pull converter involved in a half-bridge. PFC The control circuit for the corrector power factor was chosen MC34262 The involvement of this circuit in the design corresponds to the wiring shown in the data sheet. During the operation of the control circuit…
The power output stage in class D amplifier is implemented using two integrated circuits from the company Texas Instruments – TPA3118D2 for the right and left channel and the TPA3116D2 for the channel of the subwoofer. Stereo channels delivering maximum power output 2×30W into loads of 8 Ω and a subwoofer 100W to a load…
IRS2092 2X50W Class D Amplifier Project The objective of this work is the design and implementation of the amplifier of class D with an output power 2 x 50 W at the impedance load of 4 Ω and a maximum total harmonic distortion of 10 %. In work is described the principle of operation of…
NCP1380 fixed switching frequency of the driven circuit NCP1236 and changer using the effect of switching at a minimum voltage (valley switching) with the controller NCP1380. For the needs of comparison was designed a test board with NCP1380. Design resources comes from the 65 W adapter with controller NCP1236 described in the application note .…
0-30V 0-6A Adjustable Laboratory power supply LCD Display ATmega16 controlled The basic involvement of the entire laboratory resources. Ac mains voltage 230V is transformed into two equal dc voltage 35V and also on the two voltage with a value of 5V for various polaritách. To a voltage of 35V is connected part of the Active…
