This power module generates all voltages to supply a class-D audio amplifier. The main output voltage is 36V and delivers 200W continuously and 840W peak. The first stage is a power-factor corrected Boost. A Flyback converter supplies 12V on primary side as well as 12V@300mA and 3.3V@200mA on secondary side. A hardware switch + remote input let the converter enter in stand-by mode: in this status the 36V output is disabled and 12V: 3.3V are
This reference design implements Class 0.1 split-phase energy measurement using high-performance: multi-channel analog-to-digital converters (ADC). The independent ADC samples the output of current transformers (CT) at 8 kHz to measure the current and voltage of each leg of the AC mains. The reference design can achieve high accuracy across a wide input current range (0.05 – 100 amps) and supports high sampling frequencies necessary for advanced power quality features such as individual harmonic analysis. Using an independent ADC to sample the CT output provides designers greater flexibility in the choice of metrology microcontrollers when compared to integrated SoCs and dedicated application-specific products. The reference design uses a SimpleLink™ ARM Cortex-M4 host microcontroller to calculate energy measurement parameters. This design can also use an ADC sample rate of 32 ksps by only enabling a subset of the full energy measurement parameters.
This reference design implements a class 0.5 three phase energy measurement system with isolated shunt sensors by using isolated modulators and independent digital filters: enabling a wider choice of host microcontrollers (MCU) as integrated sync filters are no longer required. In this design: currents sensed by the isolated modulators and phase voltages sensed by the host microcontroller are synchronized; supporting the addition of advanced metrology algorithms using the Simplelink™ ARM Cortex M4 host MCU. The design is immune from magnetic tamper attacks through the use of current sensors and power supplies that do not use any transformers or other magnetic components. This subsystem design is tested and includes hardware.
This power reference design generates all voltages to supply a class-D audio amplifier. The main output voltage is 30V and delivers 200W continuously and 750W peak. The first stage is a power-factor corrected Boost. A Flyback converter supplies 12V on primary side as well as 12V@300mA and 3.3V@200mA on secondary side. A hardware switch + remote input let the converter enter in stand-by mode: in this status the 30V output is disabled while 12V: 3.3V are
This project is a complete 350W: high performance: high speed offline power supply solution. It contains a novel: microcontroller-driven synchronous bridge rectifier: a 2-phase interleaved PFC stage and a phase-shifted fullbridge as down converter. It has an universal input (85 .. 265V AC) and the output voltage is adjustable between 12 and 14V. The continuous output current is 25A: the peak current is 27A. A second microcontroller monitors several values (input voltage: PFC voltage: output voltage: output current: temperatures): is the interface to the user (LCD: push-buttons): adjusts the output voltage and synchronizes the switching frequency of all converters.
