INVERTER HVC-300 - 600V

HVC-300 — 300 kW high-voltage dual-drive inverter

The HVC-300 from XAP Technology is a high-voltage inverter developed for motorsport programmes, prototypes and high-performance electric vehicles. From a single enclosure, it controls two independent three-phase motors or one three-phase or six-phase machine. With 300 kW of continuous power, liquid cooling and auxiliary control functions, it suits demanding architectures, while the integrated calibration tool streamlines torque and speed tuning.

Within a 12 kg enclosure, the HVC-300 combines motor control, two independent CAN-FD buses, auxiliary inputs and outputs, and several position sensor interfaces. In a twin-motor configuration, this architecture reduces the number of control units and can shorten the wiring harness, while giving integrators the freedom to build a modular powertrain.

The integrated Motor-Editor tool supports live mapping through three access levels — Basic, Standard and Expert — to assist development from prototype to series production. Additional inputs and outputs also enable the HVC-300 to control auxiliaries such as pumps, valves and fans, depending on the vehicle configuration.

Key features

• 300 kW continuous power at 600 V and 340 kW peak power.
• Controls two independent three-phase motors or one three-phase or six-phase machine.
• Continuous phase current up to 1,000 Arms and peak phase current up to 1,200 Arms.
• Two independent CAN-FD buses and an isolated USB interface for configuration and diagnostics.
• Supports resolver, Hall, sin/cos, digital SSI and digital encoder feedback.
• Liquid cooling, IP65 ingress protection and an operating temperature range of −40 °C to +85 °C.

Technical specifications and integration

The HVC-300 integrates into a 500 to 700 V high-voltage architecture. XAP can support the definition of power interfaces, signal harnesses, CAN communications and motor calibration. Before power-up, the integrator must validate cable and protection ratings, cooling, interlocks, CAN termination, and the compatibility of the motor and its sensors with the selected configuration.

Electrical and system integration

The battery connects to high-current studs or plate terminals, while six phase terminals provide the U, V, W and X, Y, Z outputs in dual-drive mode. The J1 signal connector, identified by TE reference 1-776230-1, carries the two CAN networks, USB, motor position feedback, analogue inputs and the power command. CAN frames are documented in DBC format. USB supports configuration, diagnostics and firmware updates.
