Many appliances today use non-isolated power supply to furnish low output power required to run a micro, LED display, and a few relays or AC switches. This type of power supply has a single rectifier so as to reference the neutral to output ground in order to fire TRIACs or AC switches.View Design
The UCC28600 evaluation module (EVM) is a 120-W off-line quasi-resonant flyback converter providing a 19.4-V regulated output at 6.2 A of load current, operating from a universal ac input.
The front-end power factor correction (PFC) stage is controlled by the UCC28051 and accommodates an input line voltage range of 85 VRMS to 265 VRMS and is designed to meet EIC61000-3-2 harmonic em…
This user manual describes a high efficiency solution for industrial power supplies with a continuous output power of 150 W and peak power up to 240 W. It takes advantage of the resonant approach to minimize switching losses, resulting in higher than 90% efficiency. The topology is based on half-bridge and operated in a resonant fashion by means of a resonant LC tank, driven by the L6599 dedicate…View Design
* From page 10 of AN954:
Figure 10 shows a capacitive power supply with several UL considerations designed in. A fuse is added to protect the circuit during an over-current condition.
Adding R2 in parallel with C1 creates a filter that will attenuate EMI from traveling back onto the line. A varistor, or MOV, provides transient protection.
Advantages of C…
The purpose of this application note is to explain the design of an 80 W 3-phase auxiliary power supply for motor drives and welding applications. To reach a high level system in terms of both efficiency and cost, the L6565 PWM controller has been selected as well as the STC04IE170HV as the main switch. The combination of these STMicroelectronics parts provides a highly efficient solution for hig…View Design
The VIPer53 combines an enhanced current mode PWM controller with a high voltage MDMesh Power Mosfet in the same package. VIPer53 is available in two different packages, DIP-8 and PowerSO-10. This reference board is an offline wide range power supply that incorporates VIPer53 and is set up for secondary regulation by driving the PWM controller through an optocoupler.View Design
