Massive Decline in IREDA/PFC/REC Stocks - Time to buy? | PFC Full Analysis | Rahul Jain #stocks
Why IREDA/PFC/REC stocks are declining? Is it a good time to buy the dip or should we wait for more corrections in these stocks? What is the long term outlook for PFC stock? Which is a better stock PFC or REC? Is IREDA overvalued? Is IREDA a good stock? I answer some of these questions in this video.

High-Power PFC: Totem-Pole PFC vs. Interleaved Boost PFC
Modern power supply designs require advanced power factor correction (PFC) circuitry to meet strict power factor (PF) standards while maintaining high efficiency and low cost. Interleaved boost PFC is the most commonly used PFC topology, but the advent of wide-bandgap semiconductors has enabled the implementation of bridgeless topologies like totem-pole PFC. This video explores the composition and advantages of interleaved boost PFC and totem-pole PFC topologies for high-power PFC converter applications. Boost PFC has more switches and larger conduction losses, but can offer advantages in size and cost. Totem-pole PFC offers greater efficiency and performance for high-power applications. Watch to learn which topology is best for your design.

in this video i explained 3500 Watt / 3.5 KW PFC Power Factor Correction Reference Design Circuit - Explained This reference design is a 3.5-kW, cost competitive PFC designed for room air conditioners and other major appliances. This reference design is a continuous-conduction-mode (CCM) boost converter implemented using TI’s UCC28180 PFC controller provided with all of the necessary built-in protections.
System Description
Major appliance equipment such as air conditioners, refrigerators, and washers use three-phase, pulse width modulated BLDC or PMSM drives. These motor drives typically have fractional or low horsepower ratings ranging from 0.25 HP (186 W) to 5 HP (3.75 kW). An electronic drive is required to control the
stator currents in a BLDC or PMSM motor. A typical electronic drive consists of:
• Power stage with a three-phase inverter with the required power capability
• Microcontroller unit (MCU) to implement the motor control algorithm
• Motor voltage and current sensing for closed-loop speed or torque control
• Gate driver for driving the three-phase inverter
• Power supply to power up the gate driver and MCU
These drives require a front-end power PFC regulator to shape the input current of the power supply and
to meet the standards for power factor and current THD, such as IEC61000-2-3. A PFC circuit shapes the
input current of the power supply to be in phase with the mains voltage and helps to maximize the real
power drawn from the mains. The front-end PFC also offers several benefits:
• Reduces RMS input current
For instance, a power circuit with a 230-V/5-A rating is limited to about 575 W of available power with a
power factor (PF) of 0.5. Increasing the PF to 0.99 almost doubles the deliverable power to 1138 W,
allowing the operation of higher power loads.
• Facilitates power supply hold-up
The active PFC circuit maintains a fixed, intermediate DC bus voltage that is independent of the input
voltage so that the energy stored in the system does not decrease as the input voltage decreases. This
maintenance allows the use of smaller, cost effective bulk capacitors.
• Improves efficiency of downstream converters
The PFC reduces the dynamic voltage range applied to the downstream inverters and converters. As a
result, the voltage ratings of rectifiers can be reduced, resulting in lower forward drops. The operating
duty cycle can also be increased, resulting in lower current in the switches.
This reference design is a boost PF regulator implemented using the UCC28180 device as a PFC
controller for use in all appliances that demand a PF correction of up to 3.5 kW. The design provides a
ready platform of an active front-end to operate downstream inverters or DC/DC converters operating on a
hi-line AC voltage range from 190-V to 270-V AC.
This design demonstrates a high power density PF stage in a small form factor (215 × 145 mm) that
operates from 190-V to 270-V AC and delivers up to 3.5 kW of continuous power output to drive inverters
or converters at more than a 98% efficiency rate without an SiC device. This TI Design also provides
flexibility for the boost follower configuration, in which the boost voltage can be varied with AC input
voltage, but only can work on the boosted voltage when it is above the peak input voltage. The boost
follower configuration helps reduce switching losses in the PFC regulator and the downstream inverter or
converter. This design also gave an efficiency comparison in using MOSFET and IGBT, which can help
customer to choose efficiency or cost is preferred.
Above all, this TI Design meets the key challenges of appliances to provide safe and reliable power with
all protections built in while delivering a high performance with low power consumption and a very
competitive bill-of material (BOM) cost.

• Improves efficiency of downstream converters
The PFC reduces the dynamic voltage range applied to the downstream inverters and converters. As a
result, the voltage ratings of rectifiers can be reduced, resulting in lower forward drops. The operating
duty cycle can also be increased, resulting in lower current in the switches.
This reference design is a boost PF regulator implemented using the UCC28180 device as a PFC
controller for use in all appliances that demand a PF correction of up to 3.5 kW. The design provides a
ready platform of an active front-end to operate downstream inverters or DC/DC converters operating on a
hi-line AC voltage range from 190-V to 270-V AC.
This design demonstrates a high power density PF stage in a small form factor (215 × 145 mm) that
operates from 190-V to 270-V AC and delivers up to 3.5 kW of continuous power output to drive inverters
or converters at more than a 98% efficiency rate without an SiC device. This TI Design also provides
flexibility for the boost follower configuration, in which the boost voltage can be varied with AC input
voltage, but only can work on the boosted voltage when it is above the peak input voltage. The boost
follower configuration helps reduce switching losses in the PFC regulator and the downstream inverter or
converter. This design also gave an efficiency comparison in using MOSFET and IGBT, which can help
customer to choose efficiency or cost is preferred.
Above all, this TI Design meets the key challenges of appliances to provide safe and reliable power with
all protections built in while delivering a high performance with low power consumption and a very
competitive bill-of material (BOM) cost.

What is power factor? In this video we learn all about power factor starting at the basics. We cover, what is power factor, what is good and bad power factor, how to fix bad power factor, what is leading power factor, what is lagging power factor, how capacitors, inductors and resistors affect circuits as well as how to calculate the power factor correction.
