7 Critical Steps In Switching Power Supply Design
A Practical Approach We made some measurements using a standard forward switching power supply based on a UC3844 specialized IC. The load was a 10 ohms resistor in series with a 10mH inductance.... Quick snubber design: To achieve significant damping C s > C p. A good first choice is to make C s equal to twice the sum of the output capacitance of the switch and the estimated mounting capaci- tance. R s is selected so that R s =E o /I o. This means that the initial voltage step due to the current flowing in R s is no greater than the clamped output voltage. The power dissipated in R s can

switchmode power supply transformer design Historically most transformers have been designed to run at a temperature of 40 to 60º C above ambient and therefore it was useful to minimize losses in the 60 to 100º C operating temperature range....

Controller IC 2. High Side MOSFET 3. Catch Diode or Low Side MOSFET 4. Inductor 5. Resistors and Capacitors for feedback, compensation, and other filtering Depending on the type of SMPS, either a catch diode or a low side MOSFET will be used

- The ‘Switched Mode Power Supply’ owes its name to the dc-to-dc switching converter for conversion from unregulated dc input voltage to regulated dc output voltage. The switch employed is turned ‘ON’ and ‘OFF’ (referred as switching) at a high frequency. During ‘ON’ mode the switch is in saturation mode with negligible voltage drop across the collector and emitter terminals of
- poor power supply design. Good power supplies support a range of output current from Vout while holding the output voltage constant. In a resistor-based design, if there is any load current then the voltage drop across Z 1 will increase and Vout will correspondingly decrease, which is undesirable. Another issue is that if Vin were to decrease, then V out will decrease by the same proportion
- switching power supply design. However, there are a few notable differences: 1. The frequency of the PWM generated by the PIC16F785 is programmable using the phase counter and prescaler within the analog PWM peripheral. 2. The phase delay between the PWM pulse out-puts PHA and PHB programmable in the PIC16F785. 3. The PWM module in the PIC16F785 can gener-ate up to 2 …
