.. and, therefore, the source of 100% error. The obvious approach, using larger resistors, works poorly when you need high-frequency performance. The resulting RC delay products can cause frequency peaking, ringing, and, sometimes, ...
.. and transfer cycle that takes the load to its final voltage. Any attempt to design the converter using a fixed switching frequency results in poorer efficiency. In the case of higher switching frequency, energy transfer would be ...
.. be minimized to reduce power dissipation. For a quick charge of Q2’s gate capacitance C G during turn-on, oscillator frequency should be high (it’s about 900 kHz here). For quick turn-off, R5 should not be too high: the time ...
.. only the coaxial cable between the receiver and the dish to send commands for actions such as changing the low-noise-block frequency range or switching between dishes for multisatellite reception. The DISEqC protocol specifies a bit ...
.. mode, the sum of on-time and off-time gives the switching period of the 1200AP60: where f S is the switching frequency. Extracting L 1 yields If you select a ripple current of 20 mA peak-to-peak at 380 V dc, then From this ...
.. Reference 1 ) or DDS (direct digital synthesis). Digital techniques provide higher stability and the ability to incorporate frequency, phase, and amplitude adjustments. For applications requiring 16-bit or higher-resolution, ...
.. converter in applications in which power efficiency is a critical issue. The two phases of operation repeat periodically at frequency f, which clock generator IC 2 determines. The duty cycle is about 50%, but the value isn’t all ...

.. between V 1 and V 2 and therefore has an inherent dc level that can filtered using a simple RC-network with a low cut-off frequency, e.g., 2 Hz if needed. Filtering guarantees square-wave output with negligible peak level attenuation ...
.. and only uses a few components. Basically, it is an Arduino Uno based PWM controller that operates at a relatively high frequency (Figure 1). It features almost 0-100% DC motor speed regulation while retaining the pulse width ...
