The Popular Technologies of Power Conversion 

► Zero-Voltage-Switching Phase-Shifted Full-Bridge Converter 

• Reduced switching losses – zero-voltage switching 

• Fixed frequency 

• Suit for isolated power converter 

► Resonant Converter (FSL-LLC) 

• Low switching losses 

Transistor turn-on occurs at zero voltage - Zero-voltage switching 

Transistor turn-off occurs at zero current – Zero-current switching 

• Reduce converter-generated EMI 

• Variable switching frequency which range can be very large 

• Not good for input voltage variation 

• Not good for filter design 

► Multiple-Phase DC/DC Buck Converter 

• Input/output ripple cancellation 

• Less input/output capacitance needed 

• Reduce power dissipation and improve efficiency 

► Interleaved PFC (Power Factor Correction) 

• Transition mode and continuous current mode 

• Inductor volume reduced 

• The ripple-current cancellation at the input of the power converter, reduced 

conductive loses due to current ripple 

• Alleviating electrical overstress on capacitor 

• Redundant phases can be shut down for efficient operation 




TM

The Challenges of Power Conversion Design 

Increased performance and cost pressures 

Pressure to increase performance while reducing cost to 

meet customer demands 

System complexity 

On the rise with the need for more features and 

Functionality in smaller form factors 

Time to market constraints 

Increasingly complex development environments and 

design cycle time-frames that are constantly shrinking 

Scalable & Compatible 

Easy migration from existing product with common 

core, IP and tools

What Is Digital Control 




TM

Where Is Digital Power Conversion Applied 

“Digital Power Conversion” is a power system that is controlled by 

digital circuits, in much the same way as would be with analog 

circuits, to monitor, supervise, communicate and control looping. 

A fully digitally controlled power system includes both 

“Digital Control” and “Digital Power Management” 

Digital Control 

Power switch control feedback or feed 

forward loop,which is controlled by the 

digital circuit or programmable controller 

regulates the output of the power system 

by driving the power switch duty cycle 

using pulse width modulation techniques 

Advanced adaptive control system,the 

control circuits combine A/D conversion, 

pulse width modulation,communication 

interfaces, operating entirely or mostly in 

digital mode to gain excellent system 

performance 




Digital Power Management 

A digital circuit or programmable controller 

provides the functions of configuration, 

diagnosis, monitoring , protection, supply 

sequencing, and communication with the 

Environment.

►Proportional Control 

• Error multiplied by constant 

• Deals with present behavior 

output = pGain * error 

►Integral Control 

• Accumulates long-term precision 

• Takes longer to settle, but provides 

better precision 

• Deals with past behavior 

iState = iState + error 

output = iGain * iState 

►Differential Control 

• Predicts behavior 

• Provides better stability 

output = dGain * (current_position – previous_position)

INIT ($FF00)

Center Aligned Example 

When the Init value is the signed negative of the Modulus value, the PWM module 

works in signed mode. Center-aligned operation is achieved when the turn-on and 

turn-off values are the same number, but just different signs.

CH0 CH0b CH0 a 




Edge Aligned Signed Mode Example 

All PWM-on values are set to the init value, and never changed again. 

Positive PWM-off values generate pulse widths above 50% duty cycle. 

Negative PWM-off values generate pulse widths below 50% duty cycle. 

This works well for bipolar waveform generation.

In this example, both PWMs have the same duty-cycle. 

However, the edges are shifted relative to each other by 

simply biasing the compare values of one waveform 

relative to the other. 




Phase Shifted PWMs 

Alternatively, if the waveforms are 

generated by different sub-modules, the 

waveforms can be shifted by simply 

changing the Init value of one sub-module 

relative to the other. 

This is useful for reconstructing phase currents from a DC bus shunt 

when the amplitudes of the modulated signals are near zero.

► Challenge: 

Challenge of Controlling Resonate Converter 

• Wide range of PWM switching frequency from 100KHz up to 1Mhz 

• Need to make a change to the PWM period without changing the duty cycle for up to 4 channels of 

PWM within one period of the existing PWM 

• PWM period change must be in a few nanosecond 

► Solution: 

• High speed digital PWM plus Analog edge delay 

• PWM duty cycles are calculated by high speed controller 

• Special circuit is used to automatically increment the PWM period by repositioning edges 

Original PWM 

Initial PWM period 

Modification to both PWM edges

duty cycle and 

frequency makes variable 

frequency control and high 

switching frequency easier, 

and help reduce input/output 

ripple and system volume

► Once 

• The ADC starts to sample just one 

time whether you use the START bit 

or by a sync pulse. This mode must be 

re-armed by writing to the ADCR1 

register again if you want to go 

capture another scan 

► Triggered 

• Sampling begins with every 

recognized START command or sync 

pulse 

► Loop 

• The ADC continuously take samples 

as long as power is on and the STOP 

bit has not been set 

► Sequential Mode 

• Sequential will sample SampleN one 

after another. Channel ANAx are 

sampled by ADCA and Channel ANBx 

are sampled by ADCB 

► Parallel Mode 

• Simultaneous: Parallel can sample 

SampleN from Group1 and SampleN 

from Group 2 at the same time. 

• Independent:: ADCA and ADCB can 

operate independently. At end of scan 

of each ADC, they generate separate 

interrupt request.

►Description 

Pancake PMSM Sinusoidal Sensorless Demo 

Key Features 

►Presented demo of sensorless control maintains the electric drive performance and requires no 

mechanical position or speed sensor. Application of this sensorless control allows generation 

throughout motor whole speed range starting from zero up to the nominal speed and even motor 

reversal is achievable. The control of PM motor is based on field oriented control with implemented 

speed control loop. This includes inner current control loop with implemented decoupling of crosscoupled 

variables achieving good torque control performance. Application is a single chip solution 

based on MC56F80xx digital signal controller series without any additional supportive circuitry. 

The demo consists of the pancake PMSM and motor load, control board based on MC56F8013/23 

and high voltage power stage.

The Tower System is a simple concept. Take basic 

hardware modules, connect them together and start 

designing. There are two types of hardware modules, 

MCU/MPU and peripheral (i.e. serial, memory, LCD, 

etc.), which plug into backplane "elevator" boards. 

Through the use of open software and a standardized 

form factor and signal list, we, along with our 

customers and our partners, can continually design 

new modules to meet your design requirements. 

These new modules can be used for future product 

development. 

Features: 

• Multiple modular boards provide easy-to-use, reconfigurable 

hardware 

• Interchangeable peripheral boards make it easy to customize 

your design 

• Open source hardware and software speeds development 

• Microcontroller modules include Open Source BDM debug 

hardware 

• Each microcontroller module is a standalone BDM debug tool

• General Function Library (GFLIB) contains math, trigonometric, look-up table and control functions. These software 

modules are basic building blocks. 

• Motor Control Library (MCLIB) contains vector modulation, transformation and specific motor related functions to build 

digitally controlled motor drives. 

• General Digital Filter Library (GDFLIB) contains filter functions for signal conditioning. 

• Advanced Control Library (ACLIB) will contain functions to enable building the variable speed AC motor drive systems 

with field oriented control techniques without position or speed transducer (will be available soon).
