DC/DC conversion

DC/DC conversion is the conversion of a fixed DC voltage into a variable DC voltage, also known as DC chopper. Chopper working mode has two ways, one is pulse width modulation mode, TS is unchanged and TON(general) is changed, the second is frequency modulation mode, TON is unchanged, Ts is changed (easy to produce interference). The specific circuit consists of the following categories:

(1) Buck circuit -- buck chopper, whose output average voltage

(2) Boost circuit - boost chopper, its output average voltage

(3) Buck-boost circuit -- Buck or Boost chopper, which

(4) CUK circuit - step-down or boost chopper, its output average electricity

The above is the non-isolation circuit, the isolation circuit has forward circuit, fly back circuit, half bridge circuit, full bridge circuit and push-pull circuit.

Today's soft switching technology makes DC/DC have a qualitative leap, VICOR designed and manufactured of a variety of ECI soft switching DC/DC converter, its maximum output power is 300W, 600W and 800W etc. The corresponding power density is (6.2,10,17)W/cm3, the efficiency is 80~90 %. Japan Nemic Lambda company's latest launched a high frequency switching power module RM series using soft switching technology with the switching frequency of (200 ~ 300)kHz, and power density has reached 27W/cm3, the use of synchronous rectifier (MOS and FET instead of SCHOT diodes) makes the efficiency of the entire circuit increased to 90%.
