Switching controller with reduced inductor peak-to-peak ripple current variationA switching controller having an over voltage protection circuit is disclosed. The over voltage protection circuit detects whether the output voltage is higher than an over voltage threshold and turns on the rectifier when ...
Since the capacitor current can reflect load variations faster than the peak inductor current, incorporating the capacitor current into control loops helps... V Averneni,ST Tummuri,A Chakravarty,... - 《Ifac Papersonline》 被引量: 0发表: 2024年 Interleaved ZVS Converter With Ripple-Current Cancel...

Ideally, the DC and AC components of input current to the buck stage are provided by the input voltage source and the input capacitors, respectively. Neglecting inductor ripple current, the input capacitors source current of amplitude (IOUT – IIN) during the D interval and sink IIN during ...
Still using the PCM CCM buck as the example, the entire regulator has been modeled into the Laplace transfer function block diagram, as shown in Figure 3. There are two control loops: the voltage loop and the current loop. In the current loop, inductor current is sensed by RT and s...
required of the inductor in the LC filter14, as well as the higher current rating that other system components must accept, such as transistors, capacitors, and other components. In addition, the power loss will be greater due to the higher current, both through heating and parasitic ...
