Onstate 225: eBay China Switching DC-DC Converters Lacking Stability in Design
Switching DC-DC Converters from China are low cost and functional most of the time for many power electronic applications. It can cost 5-10 times more to make/order a similar unit from Digikey. One thing that is common to nearly all low-cost Chinese DC converters is the omission of a few critical parts to make it from a product that is going to smoke or One-Hung-Lo to a product that is smoking the competion. It is usually the regulator feedback stability that is the main issue. Search Onstate Youtube channel for testing of various DC-DC converters. Subscribe for technical support.

Boost converter simulation/modelling using simulink MATLAB. A boost converter (step-up converter) is a DC-to-DC power converter with an output voltage greater than its input voltage. It is a class of switched-mode power supply (SMPS) containing at least two semiconductors (a diode and a transistor) and at least one energy storage element, a capacitor, inductor, or the two in combination. Filters made of capacitors (sometimes in combination with inductors) are normally added to the output of the converter to reduce output voltage ripple.

Maximum Boost Control of Diode Assisted Buck–Boost Voltage Source Inverter with Minimum Switching Fr
Maximum Boost Control of Diode Assisted Buck–Boost Voltage Source Inverter with Minimum Switching Fr Diode-assisted buck-boost voltage-source inverter achieves high voltage gain by introducing a switch-capacitor based high step-up dc-dc circuit between the dc source and inverter bridge. As for the unique structure, various pulse width modulation (PWM) strategies are developed with regard to the chopped intermediate dc-link voltage. In order to maximize voltage gain and increase efficiency, this paper proposes a novel PWM strategy. It regulates the average value of intermediate dc-link voltage in one switching time period (Ts) the same as the instantaneous maximum value of three-phase line voltage by controlling the front boost circuit. Then, the equivalent switching frequency of power devices in the inverter bridge can be reduced to 1/3fs(fs = 1/Ts). The operating principle and closed-loop controller design are analyzed and verified by simulations and experiments. Compared with existing PWM strategies, the new control strategy demonstrates less power device requirement and higher efficiency in high voltage gain applications. It is a more competitive topology for wide range dc/ac voltage regulation in renewable energy applications. Furthermore, with new control strategy, the dc-side inductor current and capacitor voltage contains six-time line-frequency ripples. To overcome the undesired influence of low frequency ripples, it is also suitable for 400-800 Hz medium frequency aircraft and vessel power supply system.

DC - DC Converter  Failure analysis - Electronic Repair
This DC converter had worked for about one year before failing. It was powering an antenna and Ethernet switch which drew around 0.5 Amp.The input voltage was nominally 12 volts from a solar panel and the output 24 volts. The converter is based on the common UC3843 chip.With no load the unit operates OK with 24 volts output. As soon as the load is applied the output voltage drops. On visual inspection the problem appears to be the input capacitor. Examining the capacitor under a microscope confirms it is damaged. The capacitor is also tested with a capacitance meter and an ESR meter. The capacitor is replaced and the converter tested for correct operation.

CH2 (bottom trace): Switching inductor. Load: 6.0 ohms power resistors. Testing Results: Test1: Boost mode (boost to 36V output). N-CH MOSFET gate: 5.3Vgate, 13.4Vp-p Vspike, 100kHz switching frequency, acceptable square wave. Inductor: Constant 36V switching, some ringing. Test2: Buck mode. P-CH MOSFET gate: 10.5Vgate, 13.4Vp-p Vspike, 68kHz switching frequency, clean stable square wave. Inductor: Constant 36V switching, stable square wave. Output: 0-32.0V output, 100-150mVp-p output ripples, 1.8Vp-p Vspikes. Stable switching. -83%-90% overall efficiency. -Stable output voltage. -Voltmeter measurements acceptable. -Extra filter inductor and capacitor required to filter output switching voltage spikes. -Output power start-up is quick and stable with minimal overshoot. -Quick input power loss will cause the module to reboot. -Good for resistive loads. -Fairly quick load transient response. Recommendation: Good overall design/layout. Functions as designed. Good overall efficiency. Output noise may cause interferrence with load electronics. Pass preliminary testing as a good, economical hobbyist programmable power supply. UPDATE: Further testing suggests that the module is best for resistive loads and loads in constant voltage operation. Constant current battery charging maybe acceptable. Constant current LED loads works best with LED panel connected before module power-up. If module output power is on without the LED module connected, LED module failure may occur due to high surge current from slow feedback response. Subscribe for technical support.
