Abstract

A boost DC-DC converter with continuous input and output currents includes an inductor L1, a diode D1, a capacitor C1, a resistor R1, a capacitor Co and one electronic switch. The electronic switch has a port a and a port b. One end of the inductor L1 is connected to the positive end of a DC power supply Vi, the other end of the inductor L1 is connected to both the anode of the diode D1 and the port a of the electronic switch, the cathode of the diode D1 is connected with one end of the capacitor C1, one end of the capacitor Co and one end of a load Z, the port b of the electronic switch is connected to the other end of the capacitor C1 and one end of the resistor R1, the other end of the load Z is connected to the other end of the capacitor Co, the other end of the resistor R1 and the negative end of the DC power supply Vi. The converter has the following working characteristics: the input and the output currents are continuous, the output voltage is greater than or equal to the DC power supply voltage, and the output voltage and the DC power supply voltage have the same polarity.

Description

technical field [0001] The invention relates to a direct current-direct current (DC-DC) converter, especially a step-up DC-DC converter with continuous input and output currents and the same polarity of input and output voltages, which can be used as a basic unit to form multi-input and Multi-output DC power system, such as: DC power module parallel system, LED array drive system, distributed photovoltaic power generation system, etc. Background technique [0002] The existing basic DC-DC converters with boost function include Boost converter, Buck-Boost converter, Cuk converter, Sepic converter and Zeta converter. As listed in Table 1, without considering the output capacitor, none of the above five basic DC-DC converters with a step-up function satisfies the requirement of "both input and output currents are continuous and input and output voltages have the same polarity". Require. [0003] [0004] Table 1. Contents of the invention [0005] In order to overcome t...
