Product details

Overview

STEVAL-ISV001V1 from STMicroelectronics is a 1000 W dual-stage DC-AC demonstration board implementing a push-pull DC-DC stage followed by a sinusoidal H-bridge PWM inverter, delivering 230 V_rms/50 Hz output from 24 V nominal DC input (20–28 V range), with 90% peak efficiency and galvanic isolation for UPS and off-grid PV systems.

For engineers reviewing the STEVAL-ISV001V1 datasheet, STEVAL-ISV001V1 pinout, STEVAL-ISV001V1 application, or STEVAL-ISV001V1 equivalent, this board provides validated reference design implementation of high-frequency (100 kHz DC-DC / 16 kHz inverter) dual-conversion topology using STP160N75F3 MOSFETs, SG3525 PWM controller, and L6386SD gate drivers - critical for rapid prototyping of battery-backed or solar-powered AC inverters.

Technical Context

The board implements a two-stage conversion architecture: first, a regulated high-voltage DC bus is generated via a push-pull DC-DC converter operating at 100 kHz with transformer-based galvanic isolation; second, an H-bridge inverter stage uses sinusoidal PWM at 16 kHz to synthesize a low-distortion 230 V_rms, 50 Hz sine wave output.

Control is distributed across three ICs: SG3525 governs the DC-DC stage with adjustable oscillator frequency and soft-start; ST7FLITE39 microcontroller manages inverter timing, protection logic, and synchronization; dual L6386SD high- and low-side gate drivers deliver matched 1.5 A peak drive current with integrated diagnostics and bootstrap management.

Key Specifications

Parameter	Value and Actual Design Meaning
Nominal Input Voltage	24 V DC, operational range 20–28 V - supports lead-acid or LiFePO₄ battery banks common in UPS/PV systems.
Output Voltage / Frequency	230 V_rms ±2%, 50 Hz ±0.1 Hz - meets EN 50160 voltage/frequency tolerance for grid-connected standby applications.
Maximum Output Power	1000 W continuous - sufficient for critical loads including refrigeration, lighting, and telecom power supplies.
Peak Efficiency	90% at full load - achieved via synchronous rectification-free push-pull topology and optimized MOSFET switching (STP160N75F3, R_DS(on) = 7.5 mΩ).
DC-DC Switching Frequency	100 kHz - enables compact magnetics (T1/T2/T3 transformers) and reduced EMI filter size.
Inverter PWM Frequency	16 kHz - suppresses audible noise while maintaining THD < 5% at rated load without external filtering.

FAQ

What input voltage range does STEVAL-ISV001V1 support?

The board accepts 20 V to 28 V DC input, with nominal operation at 24 V. This range accommodates standard 24 V battery systems including flooded lead-acid (20.8 V discharge cutoff) and LiFePO₄ (28.8 V full charge), enabling direct integration into UPS and off-grid solar storage without external DC-DC pre-regulation.

Does STEVAL-ISV001V1 include protection features?

Yes - it implements overcurrent detection on both DC-DC and inverter stages using discrete sense resistors and comparator circuits feeding the ST7FLITE39 MCU, which triggers shutdown within < 10 µs. Thermal monitoring is provided via NTC thermistors on heatsinks, and undervoltage lockout prevents operation below 20 V input.

Can STEVAL-ISV001V1 be modified for 115 V_rms/60 Hz output?

Yes - output voltage and frequency are software-configurable via the ST7FLITE39 firmware. Adjusting the SPWM lookup table and updating the feedback divider network (R96/R97) allows reconfiguration to 115 V_rms/60 Hz, though transformer T2 must remain unchanged as its turns ratio and core rating are designed for 230 V output.

Is galvanic isolation implemented on both conversion stages?

Yes - galvanic isolation is provided at both stages: the push-pull DC-DC converter uses transformer T1 (primary/secondary isolation), and the inverter stage employs optocoupled gate drive signals for IGBTs (M1–M4), ensuring reinforced isolation between low-voltage control logic and high-voltage AC output per IEC 62109 requirements.
