Abstract:
A buck type DC to DC converter circuit comprising,an input, coupleable to a source of substantially DC voltage, having a first terminal and a second terminal,an output, coupleable to a load, having a first terminal and a second terminal with said second terminal of said output connected to said second terminal of said input,first switch means having a first terminal and a second terminal with said first terminal of said first switch means connected to said first terminal of said output,second switch means having a first terminal and a second terminal with said first terminal of said second switch means connected to said first terminal of said output and to said first terminal of said first switch means, operable substantially in anti-synchronization to said first switch means,a first capacitor having a first terminal and a second terminal with said first terminal of said first capacitor connected to said second terminal of said first switch means and with said second terminal of said first capacitor connected to said second terminal of said second switch means,a first inductor having a first terminal and a second terminal with said first terminal of said first inductor connected to said first terminal of said first capacitor and to said second terminal of said first switch means and with said second terminal of said first inductor connected to said first terminal of said input,a second inductor having a first terminal and a second terminal with said first terminal of said second inductor connected to said second terminal of said first capacitor and to said second terminal of said second switch means and with said second terminal of said second inductor connected to said second terminal of said output and to said second terminal of said input,whereby said buck type converter circuit simultaneously provides both non-pulsating input current and non-pulsating output current.
