Online UPS reference solution
Uninterruptible Power Supply (UPS) Reference Solution with Infineon 16-bit XC166 Family Microcontrollers and DSP
Infineon Technologies offers an extensive product portfolio for Industrial Power Conversion Systems - from real time embedded Microcontrollers to Smart Power ICs which are capable to control any Industrial Control System.
The UPS reference solution is complete reference solution offering outstanding Total Harmonic Distortion (THD) performance and high efficiency to achieve excellent closed loop response.
Key features:
Online UPS: 5~20kVA single phase double conversion UPS with output transformer.
Modularized design structure includes:
Power assembly
Microcontroller board
Display panel
Battery charger
The XC164CM (16bit MCU with DSP) achieved excellent closed-loop response
50µs per interrupt for A/D conversion, Error/Offset and duty cycle calculation
THD: 53% at full load
Excellent transient response control (ICE62040-3 Dynamic Performance Classification 1)
IGBT Module – IGBT H-Bridge in ECONOPACK
Achieved lower stray inductance and reduced switch-off voltage stress on IGBT
Enhanced inrush current withstand capability
88.5% efficiency at 40KHz modulation frequency (IGBT @ 10KHz)
Powered by a high performance 16-bit XC164CM Microcontroller with DSP and the IGBT H-Bridge in ECONOPACK Module, this reference solution offers a modularized design structure that is well-suited for Online UPS development as shown in Figure 1.

Infineon’s 16-bit microcontroller offers comprehensive features with highly integrated peripherals for maximum speed and performance. Infineons 16-bit microcontrollers are the perfect choice to control any power management systems due to the advanced Capture/Compare (CCU6E), powerful Multiply-Accumulate (MAC) unit to simplify complicated DSP algorithm and optimized ADC peripherals, which are dedicated to achieve high performance in any Industrial Power logic design. Our new XC166 family devices find its success story in Consumer Inverters and Industrial UPS applications, giving superior hardware solution and performance for your Industrial system requirements.
Infineon’s ECONOPACK IGBT Modules are compact solution with low stray inductance for the double conversion UPS with full bridge topology (Figure 2).
